Description

I updated to the latest HEAD as of yesterday (2007-05-09) after the
INET6 fix.

$uname -a
DragonFly neptune.xenno.com 1.9.0-DEVELOPMENT DragonFly
1.9.0-DEVELOPMENT #135: Wed May 9 23:29:57 EDT 2007
:/home/obj/usr/src/sys/NEPTUNE i386

I got the following kernel panic:

Fatal trap 19: non-maskable interrupt trap while in kernel mode
mp_lock = 00000000; cpuid = 0; lapic.id = 00000000
instruction pointer = 0x8:0xc02f6a1e
stack pointer = 0x10:0xcade4a44
frame pointer = 0x10:0xcade4a68
code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, IOPL = 0
current process = 729 (ifconfig)
current thread = pri 6
<- SMP: XXX

It looks like the stack was corrupted but I was able to get this:

(kgdb) bt
#0 0x00000000 in ?? ()
(kgdb) info locals
No symbol table info available.
(kgdb) x 0xc02f6a1e
0xc02f6a1e <agp_intel_flush_tlb+35>: 0x81028b90

I can upload the kernel and vmcore files if absolutely necessary but
the vmcore file is 1.6GB uncompressed so if I don't need to I will
save the bandwidth.

Perhaps unrelated, but just in case. I got this out of the kernel
buffer:

[diagnostic] cache_lock: blocked on 0xdc583e28 "utils"

I have also had a cvs process hang in the "vnode" state. I was unable
to attach the process with gdb (this just seemed to hang) or get any
output from ktrace.

Thanks,
Joe Talbott
