Boot error - grubenv - USB Drive - 11.04

[mrstoney]

I'm running 11.04 off of a 32gb flash drive. Something about grub on my install is messed up. When trying to boot after a normal shutdown, I get the following errors.

error: invalid environment block
error: invalid arch independent ELF magic

I think something about grubenv under /boot/grub is being corrupted. Loggin in under Ubuntu 10, I can make my way to the files on the 11.04 flash drive and issue the following commands to make it boot normally (from https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/439784 )

# grub-editenv grubenv create
# grub-editenv grubenv set default=0

Why is this file corruption happening? How can I fix it?

I have the same problem. Can't solve it either. But I did find a pattern. Is this the same for you?

Yes, it does it every time. I have to boot from another drive and re-create the grubenv file.

Oddly, I think it will reboot just fine. It's only when I do a full shutdown that something goes wrong.

I'm going to install on another drive to see what happens.
