Panic within sound driver

[Ollivier Robert]

I systematically get the following panic since the end of March at boot
time:

Kernel trap 12 with interrupt disabled

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x65656e48XXX een8 XXX
fault code  = supervisor read, page not present
instruction pointer = 0x8:0xc01aba3a
stack pointer   = 0x10:0xc03d66ac
frame pointer   = 0x10:0xc03d66b8
code segment= base 0x0, limit 0xf, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags= resume, IOPL = 0
current process = 0 (swapper)
Kernel: type 12 trap, code = 0

Stopped at _mtx_lock_sleep+0x2e2: movb  0x1d5(%edx),%al

snd_mtxlock
ad1816_lock
ad1816mix_set
mixer_set
ad1816_attach
device_probe_and_attach
isa_probe_children

mi_startup

Any idea?

That's what I was thinking :)

Thanks, I'll just reboot now to test the patch.
