I'm seeing something similar with grsecurity-2.2.1-2.6.36.2-201012192125.patch. At first I thought it was missing the initrd, but it was there and then I thought I'd glance at the forums and saw this thread. This was going from 2.6.36-grsec (which boots fine) to 2.6.36.2-grsec, Dell PE 1950 running Debian Lenny 32-bit.

For the heck of it, I rebuilt the initrd and got this on reboot:
