It just panics my laptop (think due to another bug discovered):
Unread portion of the kernel message buffer:
info: [drm] Setting GART location based on new memory map
bus_dmamem_alloc failed to align memory properly.
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x16c
fault code = supervisor write, page not present
instruction pointer = 0x20:0xc3fc38ce
stack pointer = 0x28:0xe32f2b28
frame pointer = 0x28:0xe32f2b48
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 3
current process = 1387 (Xorg)
trap number = 12
panic: page fault
Here is the relevant backtrace part (drm kernel modules compiled w/o
debug though):
