Hello I am using a Dell Latitude D630 and once I was shutting down my computer when I got a "unable to handle kernel NULL pointer dereference at 00000018" bug followed by some messages which I typed the most below :

sda is my hard disk and I have kernel modesetting enabled.
I don't know how to reproduce this bug again, I think that is because I made some suspend to disk, suspend to RAM and resuming
before. It is new that I have linux-image-2.6.29-2-686 installed and kernel modesetting enabled. So I will see later if this bug comes with suspending.
I found almost the same bug once I was resuming from suspend to disk and removed a USB Stick during the same time (I can't
reproduce this one either) and I notice that with this one it was said :
BUG: unable to handle kernel NULL pointer dereference at 0000001c
and it has a different call trace.
