Hello folks,
I have tried it with today's -CURRENT, and as soon as I try to boot a
kernel with the options (this has occured also earlier but wanted to make
sure that I try today's sources first)
device midi
device seq
(my sound card is a ISAPnP SB 64 AWE)
I use device sbc too.
the kernel still panics with Fatal Trap 12. I have Seigo Tanimura's
fixes, and yet this still happens. I do not have a serial console, so here
a short trace output transcribed:
_mtx_lock_sleep
mpu_uartmode
mpu_attach
mprobe_attach
device_probe_and_attach
bus_generic_attach
sbc_attach
device_probe_and_attach
isa_probe_children
configure
mi_startup()
begin()
At the point of panic not even the swap partition is available yet so the
machine does not dump. How can I force it?
I would like to offer any and all help to anyone wanting to debug this; I
can reproduce the problem at will and luckily no FS corruption occurs
because the panic is so early on boot.:-)
Of course, as soon as I omit the midi part, the kernel boots fine, and the
sound card works too.
