Hi everybody,
while exiting from X windows yesterday I got the following error (the system didn't crash, thought):

waiting for X server to shut down kernel BUG at page_alloc.c:108!

To be sure I restarted the system, but I haven't notice any other problem so far... (btw, I'm using NVidia latest drivers, compiled the kernel on a Mandrake 8.2 with gcc 2.96 compiler).

And NVIDIA is the reason why propably nobody here can really help you. We don't have the source we don't know what the NVIDIA-module is doing.

Pipe your BUG through ksymoops and send the report to NVIDIA.

Two things:

(a) ask nvidia. binary modules => no help here

(b) it is not a preemption problem. that preemption error message is because X died while holding a lock and exiting with a nonzero lock count prints a warning.

Please decode it with ksymoops.
It not that important for BUGs but for real dirty oopses ksumoops is a must.
