Hi,
After updating to r238120, I get a panic whenever X starts up. It works for a few seconds, then panics. The messages don't look too useful to me, but here they are:
Unread portion of the kernel message buffer:
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 3610 (kdm_greet)
trap number = 12
panic: page fault
cpuid = 0
(kgdb) bt

Previous frame inner to this frame (corrupt stack?)
Current language: auto; currently minimal
(kgdb)
Something I saw in a previous panic made me think this was drm related, but I don't see it in this particular one.
