Has anyone else been experiencing random lockups? I've got a Pentium
with 64MB RAM, 53c810 and 53c875 SCSI adapters running NetBSD-current,
and for the past maybe 3 weeks or so, it's been locking up for no
apparent reason. At first, I was in X and thought maybe something
happened to drop it into ddb, so I quit running X and took DDB out of my
kernel. Then when it locked up, I found I couldn't even switch VTs (I
was using wscons for a while, but switched back to pcvt to see if that
was the problem). I was usually in the wrong VT to see any kernel
messages, but it did finally lock up while I was looking at vt0, and
there weren't any messages at all :( I reset the machine, and a few
times, it'd lock up again while fscking the filesystems, or later on in
/etc/rc.

I put DDB back into my kernel, and stayed out of X for a while, and I've
found that when it locks up, I can't Ctrl-Alt-Esc into DDB. So, I'm
afraid I can't give much more info about it... it just locks up :) It
might be correlated with disk access, although it's hard to tell. I've
never had it lock up while idle; it's usually during compiles and fscks.
