Re: Upgrading my Pogoplug

I'm starting to think that this isn't a problem with finding the rootfs, but more of an issue with talking to the disk from U-Boot. I created a new filesystem with the rootfs tarball, and I can't seem to boot of the disk. I keep getting timeout errors in my netconsole log.

USB0:   USB EHCI 1.00
scanning bus 0 for devices... 3 USB Device(s) found
       scanning usb for storage devices... 1 Storage Device(s) found
2461416 bytes read in 323 ms (7.3 MiB/s)
EHCI timed out on TD - token=0xd8d80
EHCI timed out on TD - token=0xd8d80
EHCI timed out on TD - token=0xd8d80
 ** ext4fs_devread read error - block

EDIT: After some more playing with U-Boot, I'm noticing there are times where it does not properly interrogate the USB disk. It is unable to read the partition info, and claims that it can't find the header signature.

PogoE02> usb part 1
 u s b   p a r t   1 

Partition Map for USB device 1  --   Partition Type: EFI

GUID Partition Table Header signature is wrong:0x0 != 0x5452415020494645
print_part_efi: *** ERROR: Invalid GPT ***

I rebooted back into my working Debian install, but this time I had both the USB stick and HDD plugged in. If I check the kernel dmesg, I see this interesting set of entries about my disks. I wonder why this drive is being detected as using 512-byte sectors?
