Anyone else having problems with feisty since this morning's update?

[Ed Smits]

I've had no problems through the various kernel updates until this
morning, installed
kernel 2.6.20-12-generic along with headers etc, can't boot into it,
had to choose the previous kernel to get up and running.

I won't be able to try and figure out what's up for a while, minor
emergency here, just wanted to know if others are seeing anything as
well
