I have current (April 11) on my i386.  I was running a perl5 script
and perl seg faulted and dumped core.  So I cded into the directory
that my perl script is it (note that cd is a shell builtin for me so
it worked).  I tried to ls....ls seg faulted.  I tried to ps...ps seg
faulted.  At this point I decided I was going to reboot real soon now
so I tried to sync...sync seg faulted.  Then I tried to quit one of my
emacs with control-x control-c...it froze.  So I tried to use the kill
window menu option in my twm menus...twm seg faulted and dumped core.
I gave up and control-alt-backspaced to get out of X because my
session gate wouldn't die (exit was seg faulting too).  X locked up my
terminal...I tried control-c and then the machine wedged.

When I gave up and reset the machine everything looked fine.  The
machine had only been up for 3 or 4 days at most and there were no
errors beforehand (I listen to syslogs *.notice).

Any ideas?

Oh and just in case this happens again...how do I drop into the kernel
debugger?...I feel bad that I can't give any more info.

...and sound started working..thanks dave...didn't even realize that I
had changed the IRQ...
