Strange panic during amd64 test run

[Paul Goyette <paul%whooppee.com@localhost>]

My test bed just encountered the following panic and crash while running 
anita/atf tests under qemu.  Since this runs with "disks" snapshots, I 
don't have the dump file to examine.

sbin/resize_ffs/t_grow (419/465): 4 test cases
    grow_16M_v0_8192:
fatal protection fault in supervisor mode
trap type 4 code 0 rip ffffffff8051560d cs 8 rflags 246 cr2  7fe94000 cpl 6 rsp 
ffff800009aacc08
panic: trap
cpu0: Begin traceback...
startlwp() at netbsd:startlwp
alltraps() at netbsd:alltraps+0xa2
xc_thread() at netbsd:xc_thread+0xd2
cpu0: End traceback...


Wondering if this looks at all familiar to anyone?
