See if this works:

In compat/linux/common/linux_ioctl.c find the line that says:

#if NSEQUENCERS > 0

and change it to:

#if 0

Ive seen a similar thing in a kernel that was built for a type of machine that
may or maynot have a sound card (long story). Basically it appears that if you
have a MIDI sequencer configured, but no sound card, one of the linux ioctl's
for termio can cause a kernel panic. (If you look at the linux emulation code,
its quite logical!)

If the above fixes things, you need to do one of two things:

a) remove the midi sequencer from your configuration file and rebuild your
kernel or
b) find out why, if you have it configured, you sound card isnt attaching a
midi sequencer.

BTW, the signal message you are seeing can be ignored. Its apparently one of
the linux signal types/handlers that NetBSD doesnt support in emulation mode,
that isnt really needed so it complains only if you have debugging on.
