I've tried to use Linaro 11.08 nano image with vexpress 11.08 hwpack but the board hangs in the init script and I never get the shell prompt.
I've used the pre-built 11.08 nano image [1] without problem. (Kernel booting from NOR, no initrd, filesystem image on a USB drive).
What kind of media is your root filesystem on? And how far is it getting (i.e. what's the last part of the serial output)?
My kernel and initrd is on the embedded flash and my rootfs on the MMC.
I've heard that due to bugs all high bandwidth devices are flakey. Specifically, MMC and SATA media are unreliable and the best solution is to try USB.
I have just copied my 11.08 image to MMC and tried booting off that. I found that it does seem to hang but after 5 minutes or so it eventually gets to the command prompt. Once booted, using ssh to copy a large file gave a transfer rate of about 30kB/s.
It's a bit odd though if you find a 11.07 image works and an 11.08 image does on the same kernel and MMC card.
