The more peripherals you have, the quicker it builds up the pool. With an old rootfs, this has not been a problem for me. I think I've seen a delay like 6 seconds is the most. Typically it takes 2 seconds. This box does not have fan, and the SDD is silent :)
For my release basic USB rootfs or HDD rootfs, I have not seen this significant delay. Typically it will take a few seconds on the first boot.
According to a few experts, haveged has not been proven to really works. The only definitive conclusion that people can tell is haveged provides very good PRNG (pseudo). But that was from long ago.
Like 1000001101000 said above, Meltdown/Spectre fix in the compiler did have an effect on CPU source of randomness. But that should have not come in to play with Kirkwood armv5 SoCs (which are not vulnerable to Meltdown/Spectre).
For our purpose, I think haveged is good enough if you want to use it. However, if you run your rootfs long enough to build entrophy, haveged is not needed. For serious purpose, people use HWRNG (hardware).

Do you use that system NFS or Samba heavily? That usually empty out your entropy pool very quickly. A lot of buffer I/Os going on with NFS (I think Samba too). You could see it by mounting NFS shares exported by that system.
You could try pluggin in a USB flash drive to do rsync back up, for example. And see the delay reduced.

I'm trying to boot from the SSD, but I'm having all kinds of problems. Sometimes it boots, sometimes it leaves me in initramfs, sometimes it kernel panics, etc. Even when it does boot, it's very unstable. Here's what I did:
I deleted the partitions on the SSD and created one ext3 partition. I copied my working USB flash file system to the SSD (tar -cpvjf ... to backup, tar xvpjf ... to restore). Then I modified the uboot environment to attempt to boot from USB first and then try IDE.

JT,
Your envs are wrong. The load addresses need to be set up the same way as booting with USB rootfs.
I will create a well organized envs set to boot both USB or SATA.

JT,
Your envs look good to me.
Now the possible problem is the rootfs label. You need to plug in a non-system USB drive to test it. And vice versa.
If you want both USB and SATA drive to have the real rootfs on each, then the partition label must be different. They should not be the same (i.e. rootfs). So if the SDD partition label is sata_rootfs, then:

JT,
See a few posts above.
Now that I recall, this stock u-boot shell is very limited. So a set of orgnanized and robuts envs might not be possible yet.

Good to know. If they are different, then a rootfs USB can be plugged in while running on the SATA drive. Right? Also, if you do this you have to update fstab as well.
BTW, I now have M300 running with a 120GB SSD; it is really snappy. I'll give an update in a couple of days.

Okay, so I need some advice or direction because I must be doing something wrong. I'm following the instructions on page 7 for Section A, which I have completed through 6, but it will never boot and just gets into a loop.
So what I think I'm doing wrong in both parts 3b and 6 for setting the environment variables, I don't believe I can copy and paste the code correctly. I can't see the full line because of screen wrapping or incorrect terminal settings? I have no idea.
Typically I use a Windows box with a Putty, but something just isn't right, so what is recommended? (OS, terminal program, terminal emulation settings, etc...)
Are you able to copy and paste all code at the same time? Line-by-line? Any help would be appreciated because I've gotten no where on this and have to start over.

So you have serial console connected? Putty with serial? Putty works fine for me, but you need to be careful that the line wraps are "clean". Maybe go full screen with the window.
I usually copy and paste from the forum; you have to drag to the right to get all of the long lines. If you go off to the right, the quote box will scroll right.
I do it one line at a time; there might be a way to do several lines, but it's "dangerous" messing with u-boot so I'm pretty careful. Proof read each line before hitting enter.
You can printenv from serial to list all of them, or printenv parameter to see a single entry. I suggest you printenv to see all and compare to the instructions. If you have it right and it doesn't work, Bohdi or someone will assist.

With the current envs we defined for this box, yes they can be plugged in at the same time. But I would recommend not to do that. It got confusing real quick. The 2 systems must be different enough (different host name, different kernel,...) so you can tell which one you are running.
In recent Debian versions, fstab is not relevant, as far as root device is concerned. The root device in bootargs always take precedent. The one we we have in fstab right now is like a fallback option.

That problem sounds like Putty terminal was not set up correctly. Check if baudrate 115200, no parity, 8 bit, 1 stop bit. And the terminal emulation usually default to some good type in Putty. But try a different one if you can.
Linux is the best OS for this. In Linux run picocom:
You can also use MAC OS. Run screen command.

I use Windows and Putty, so that's probably not the problem. Just make sure you're copying and pasting the whole line and do it one line at a time.
My thought with being able to boot from either USB or SSD was that I'd use the SSD to boot 99.9% of the time. I'd only want to boot from USB to either do a full backup of the SSD or if there was some problem with the SSD. Right now I have pretty much identical USB and SSD drives (same label) and booting from USB works great (I do have one issue, but that can wait for another time). Once booted, I can mount the SSD without issue. It's booting from SSD with no USB drive inserted that's the problem. I thought I must have the boot addresses wrong, but they should be the same. I'm starting to wonder if it's a bad SSD, although that doesn't seem likely. I just got a backup M300, so I'll have to try that one.

Thanks for the suggestions, I'll try a parted magic live boot next time with picocom and copy one line at a time.
But just one last question about the copy/paste, should I be able to see the whole pasted line in the terminal before I execute it?
Because I sure didn't last time, but I can confirm that the COM settings were matched to what you referenced bodhi.

You should see the whole line. It will wrap around on your terminal. If you cannot see the whole line, then the env was most likey got cut off, so will not work.

Children should not be allowed to play with this stuff. I tried to set up the SSD sata_rootfs and USB rootfs boot scheme and ran into a problem. It sounds similare to renojim in that the USB boots but the SSD does not.
I changed the label on the SSD to sata-rootfs and made the changes above to setup bootargs_usb and bootargs_sata. USB booted fine. SSD delayed for a while at the end of boot running, I think, local block script and then dropped into busybox with the message that it couldn't find rootfs. Seems like it did not get the sata_rootfs parameter. I also changed the fstab on the SSD to sata_rootfs, but as you noted, that should not matter.
Here is the relevant parts of my environment:
Here is the serial log for a SSD boot:
I reused the bootcmd_ide2 for sata boot, it had been working fine, rather than creating a new bootcmd_sata.
Sorry for the bother.

Well, I have two sets of M300, one had trouble with 16GB SSD SATA boot before (strange errors, even can not duplicate them.. and sometimes, success!!!??? ), the other M300, same settings, also the 16GB SATA SSD, same rootfs, no trouble at all!!!
I then changed the first set's 16GB SSD to a normal hard drive, also put a blank 64MB usb flash drive on USB port, and I can SATA boot everytime! and the system is stable!!! I put the first set's 16GB SSD on the second set (re-do the root file system) and it seems OK.
This M300 is really weird. As I mentioned, it is VERY picky on usb flash drives, maybe picky on hard drives too. :P
So if you can't do SATA boot, try two things, that might help, haha.
1 change to a "normal" hard drive, not the 16GB SSD.
2 Always put a blank usb drive (just delete all partitions, etc) on the M300 usb port.

That's unsurprising, unfortunately :) old stock u-boots sometimes have quirks like that. But it can be overcome with more env scripting. To work around the problems I need to see the serial console log when that occur.

Thanks @renojim, good eye. There was another problem on that line as well. Copy-paste difficulties and looked at these lines too many times yesterday. Fixed them and now back to the original problem of booting from a device with LABEL=sata_rootfs. Below is the serial log where it has the problem. It sticks at running /scripts/local-block.
I think this is the problem:
Looks like we need to be able to use different values here. Is this picked up from the u-boot environment? A variable? Invoke someplace else? Just give up and use rootfs for all boot capable devices?
But...
Should it be bootargs_console? But usb boot works without the underscore. I get lost in the format differences between serial and fw_printenv.
Too many things going on. I found the run still missing in the bootcmd after I thought it was fixed. On reboot, I found the boot_cmd_ide2 line had changed probably from somewhere in the envs that was triggered. It went to an address on the second partition of the stock SSD, probably their backup system. So, I need to not use ide2. I'll work on this later and get back. No need to do anything now, unless there is something really obvious.

I got a successful SSD boot correcting several environment variable at the u-boot Marvell> prompt. I had several errors. But, I'm having trouble getting the settings to "stick". I have not used saveenv in the u-boot shell. Bohdi seems to prefer waiting for the system to boot and then using fw_setenv in debian. I finally remembered that settings made in the u-boot shell do not last beyond the next boot. But setting changed in debian with fw_setenv do persist. When I do fw_printenv in debian, am I getting the environments in RAM or what is the non-volatile memory? When I try to set one of the variables from debian, I get this...
The garbage character in the first run does not appear in Putty on the serial port in debian. And, it appears the fw_setenv does not work. I cannot see a problem in the format, so what's up?
UPDATE
Got the correct environment settings to stick using savenv in the u-boot shell. Boots on both USB and SATA, and boots USB first if present. However, it looks like environment settings from debian using fw_setenv do not stick. This attempt to "erase" bootcmd2
This is an original stock variable, so perhaps it has extra protection?

root@Dell-M300:~# fw_setenv bootcmd 'run kernel_config; run set_bootargs_usb; run bootcmd_usb; run set_bootargs_sata; run bootcmd_ide' root@Dell-M300:~# fw_printenv bootcmd bootcmd=r[2~un kernel_config; run set_bootargs_usb; run bootcmd_usb; run set_bootargs_sata; run bootcmd_ide2
The garbage character in the first run does not appear in Putty on the serial port in debian. And, it appears the fw_setenv does not work. I cannot see a problem in the format, so what's up?
