X.org (AGP) related panic

[Aleksej Saushev <asau%inbox.ru@localhost>]

  Hello!

I'm observing reproducable panic with sources as of today,
ca. 10:45 MSD, no crash dump is generated, system just hangs,
handwritten backtrace follows:

uvm_pglistalloc: page not on freelist

uvm_pglist_add
uvm_pglistalloc
_bus_dmamem_alloc_range
_bus_dmamem_alloc
agp_generic_bind_memory
cdev_ioctl
spec_ioctl
VOP_ioctl
vn_ioctl
sys_ioctl

Any further directions?
