Bug Description

pandaboard A4. Booted a pre-installed image (current server 20120421); image was expanded without errors, system rebooted. On reboot I see at least two kernel OOPSes, one very early on the boot:

[ 0.000000] ------------[ cut here ]------------

and one a bit later, but still during the boot:

Rebooting shows the same sequence.

Hitting slowpath warnings in various drivers and subsystems, while unfortunate, isn't a world-ending, release-critical bug. But these sorts of things should certainly be looked at for later and considered for SRUs.
