[KLUG Members] kernel panic on new kernel in Debian for 2.6.6

[Richard Harding]

I built a new 2.6.6 kernel, but I am having a kernel panic on booting to 
it. Below is all the info I can think of. I copied most of the info from 
the existing kernel I am using right now, which is the Debian package 
for 2.6.6

If you have any ideas I would appreciate it.
