Kernel panic in 2.6.19-rc1

[Frank Sorenson <frank@tuxrocks.com>]

I'm getting kernel panics within a few minutes of boot with 2.6.19-rc1 
(latest git) on x86_64.  Other than "make oldconfig", it's an identical 
configuration to a working kernel on 2.6.18.

The panic scrolls off the screen, but I copied down what was on the screen:
