I saw something similar recently going to the first version of
2.6.36. In my case I had a USB device externally connected through a
specific USB hub. When I got rid of the hub and plugged the drive in
directly it started booting correctly again.
I don't see this with 2,6,36 with Flash drives plugged in but none
of mine are bootable.
I never investigated the root cause of why it was happening but I
suspect it's some USB kernel setting.
