SMP Problem? (was: Repeatable Hang -current SMP and lpd)

[Thomas D. Dean]

By not running X, at the console, I was able to see this to be a Fatal
Trap 12.

I can cause the machine to become non-responsive to the keyboard by
doing a 'make -j36 world', which normally takes 8 hours.  Now, this
hangs the machine between 2 and 7 hours.  Breaking into ddb, only
shows a normal console trace, scgetc() ... fork_trampoline().

df | lpr will produce a Fatal Trap 12.  I posted the details to -smp.

I built a UP kernel and it does not produce the 'Fatal Trap 12'.

Repeatable Hang -current SMP and lpd

[Thomas D. Dean]

I tried to post this before, but, I think it got lost.

I have a repeatable hang with -current when attempting to print a
region from emacs.  This happened after 2 1/2 days uptime.  The system
is frozen.  The mouse does not move the pointer.  The keyboard does
nothing - pressing Caps Lock does not turn on the LED.

On reboot, the system halts with a fatal trap 12,
when lpd starts.  The system will not get past lpd starting until I
manually remove the files from /var/spool/lpd.  Several empty err
files are generated in /var/spool/lpd.

I am running -current SMP.

Dmesg and my kernel config are attached.  What can I do to provide
more information?
