Pogoplug V4 Intermittent Freezing durting boot
February 20, 2021 02:47PM
Hi bodhi,

Occasionally, I try to ssh to Debian and find it locked up for some reason. When I reboot and monitor the boot sequence using screen over the serial input, I see its frozen.

Below is from a frozen boot.

Rhodess,

This looks like a hardware related problem (providing you already tuned your settings for swap and memory like we discussed before, and there is no other USB devices plugged in other than the 2 USB drives for rootfs and swap).

[  445.258441][	T98] usb 1-1: reset high-speed USB device number 2 using orion-ehci

What type of USB hub are you using? is it USB 2.0 or 3.0 Hub?

There are things you can do to make sure that the hub is not causing the reset such as

- Use a USB 3.0 hub attach to this Pogo V4 Mobile, and plug in both of these USB 2.0 drives.
- Or use a power hub.

For USB 2.0 hub, I like Belkin 4-port hub.

My favorite 4-port USB 3.0 hub is the Sabrent USB 3.0 brand (smaller than 1/2 pack of a cigarette and hanging off the Pogo nicely) never have problem with this. Not sure if you can find them as Sabrent (seems some other manufacters have bought this brand).

Both of these should cost less than 10 USD each.

This is the form factor I mentioned above:

https://www.amazon.com/gp/product/B012B6YQY6

They've jacked up the price for this hub too! it should be about 10 USD. Perhaps they are not making this as Sabrent or Belkin any more.

I have 2 SanDisk Cruzer Fit USB's.

I use an 8Gb as the rootfs, and the second (16Gb) where I have the swapfile and logs.

I made all those changes for swappiness and vm.min_free_kbytes, per the previous post.

I assume this is the usb with the swapfile (device number 2) that's causing the issue
[  445.258441][	T98] usb 1-1: reset high-speed USB device number 2 using orion-ehci

I'll try another usb and also see if moving the swapfile to rootfs makes a difference.

I have a SanDisk powered hub, so I'll try mounting via the hub as well.

Thanks

Look like it is.

I would do this. This box with 128MB memory should be used for tasks that don't require more than that. So best to put the swapfile on the rootfs. Add then do frequent backup.

You should also consider using zswap to make it less likely to go to disk during swapping.

Hi bodhi,

that looks like the problem. Moving the swap to the location below seems to boot slightly faster also

As for zswap, everything points to creating /etc/default/grub, since it's not present on my roots, unless it should go somewhere else for these devices?

I found the following:
enable zswap
nano /etc/default/grub
zswap.enabled=1
update-grub

Then enable compression:
echo lz4 >> /etc/initramfs-tools/modules
echo lz4_compress >> /etc/initramfs-tools/modules
update-initramfs -u

Finally, verify all is active:
cat /sys/module/zswap/parameters/enabled
dmesg | grep -i zswap

I will do it in stages

I made another search of the forum and found the following:
Pogoplug Pro V3 running vncserver. so I just added to my environment
# fw_printenv set_bootargs
set_bootargs=setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts $custom_params
# fw_printenv custom_params
## Error: "custom_params" not defined

fw_setenv custom_params 'zswap.enabled=1'

Rhodess,

Yes, this is correct (I mentioned this somewhere).

Grub is for Intel boxes. ARM boxes use u-boot or other similar boot loader.
