How to let uBoot boot directly according to UUID other than scan all usb devices?

Hello folks,

Currently I met an uBoot problem: when I connect all my disks(assorted types of partition, from ext3 to ntfs) as well as my wheezy usb stick, uboot will hang up either when loading /rescueme or when it meets the ntfs partition. Can we skip scanning all usb devices and boot directly according to assigned UUID? Thanks.

Outputs from netconsole look like below:

im looking for the same thing man its frustrating as hell

*edit*

My pogoplug v4 has this issue, my GoFlex Home does not

I'm curious: How can the uBoot find the UUID from which it is desired to boot from unless it scans the USB devices first?

well i wasnt actually looking for a uboot solution lol good point i actually want to solve the issue with kernel/ramdisk from nand if you make uboot boot a kernel from nand and have rootfs as usb it should solve the issue if im not mistaken...

*edit*

Then again i have not see anyone talking about this kidb of boot method......

restamp, I think the question was misleading. It still must scan, but since the disk UUID was already assigned before in previous boot with a single disk drive, then it can be used for the next boot. And we can do it in Debian with fw_setenv. At least how I understood it (I could be missing some details).

However, the rootfs partition label is still the most elegant solution, IMO. Because UUID is not going to be valid if we change the boot drive. But rootfs label can be set outside or inside the box if the boot drive change.
