Re: Upgrade to 3.5.0-2 kernel causes boot failure
I ddn't get that message, but I did have the nvidia graphics driver installed.
I noticed an upgrade to the grpahics driver, when updating to the 3.5.0-2 kernel, and couldn't boot into any older kernel, so I reinstalled, left the default graphics driver, and upgraded to the 3.5.0-2 kernel with no problem.
Your problem may be different, but that was mine. Hope it helps someone.
