GRUB bug

[Derrik Pates]

Booting with GRUB on three different SMP machines at my work causes an
Oops in the kernel (Linux 2.4.0-testX, and 2.4.0 final) in sk_alloc(). I
do not yet know why, but I'm trying to track it down. These kernels boot
fine with LILO, but crash reliably (100% of the time, same place) when
GRUB tries to boot them.

Kernel trace below:
