My system is a Fedora 16 x86_64 running self-compiled vanilla kernel

that starts since linux 3.2-rc5. No such corruption was noticed in
3.2-rc4. On the first instance, I eventually got a NULL pointer
dereference and the screen went black, the keyboard was unresponsive,
and I had to hard-reboot the machine. On the second instance, I managed
to reboot the machine normally. The full message log is attached. An
extract of the first WARNING:
The only patch in the i915 code between rc4 and rc5 is a tiny VT-d
workaround fix for ILK machines, which does fiddle with how the request
linked lists are managed.
Can you try reverting eb1711bb94991e93669c5a1b5f84f11be2d51ea1 and see
if your problem goes away?
Recompiled kernel with patch reverted, testing right now.
Ran kernel with reverted patch for 6 hours without issues so far. Will keep testing after work (issue happens with my home machine).
