Panics with recent i386 current

[Sverre Froyen <sverre%viewmark.com@localhost>]

Hi,

I've had a couple of panics with recent i386 current.  I do get core dumps but 
they seem to be corrupted.  Here is a back trace from the last:

(gdb) bt
#0  0xc04b6d74 in cpu_reboot (howto=260, bootstr=0x0)
    at /usr/src/sys/arch/i386/i386/machdep.c:897
#1  0xc05e980f in panic (fmt=0xc09894dc "trap")
    at /usr/src/sys/kern/subr_prf.c:292
#2  0xc0621457 in trap (frame=0xd112c8f0)
    at /usr/src/sys/arch/i386/i386/trap.c:364
#3  0xc010cc3f in calltrap ()
#4  0xc0713465 in atomic_inc_ulong ()
Previous frame inner to this frame (corrupt stack?)

Is there any additional useful information to be gotten from the core dump?

Kernel is from 24 Feb, userland a little older.

Thanks,
Sverre
