Hi!
I now have a very reproducible panic in Xorg on my 965GM (Dell Latitude
D630). No problem at the console with i915kms loaded.
vm_fault: pager read error, pid 44151 (Xorg)
Kernel page fault with the following non-sleepable locks held:
exclusive rw vm object (vm object) r =3D 0 (0xfffff80205757528) locked @
