2.6.17-rc4-mm3 cfq oops->panic w. fs damage

From: Mike Galbraith

Greetings,

I tried to boot 2.6.17-rc4-mm3 twice yesterday, and received the below
both times. Both times, the oops->panic occurred while X/KDE was
starting. KDE would not run thereafter, and had to be reinstalled.

Box is P4/HT/ICH5.
