I get these about once every 48hrs for about 2 weeks on a box I build
-current once or twice a week.
First panic here is from Wednesday, the panic at the end of this message
is from Friday morning's -current. Is there any problem currently
with dumpdev=auto and savecore? Note the silly lockheld panic when I call
doadump.
