I can't be sure it is pmap.c. See my followup debug trace on a system
crash from another -stable system.

As I mentioned in earlier mail, I have a Tyan 133mhz Pentium with 64
MB RAM that will crash if attempting to run X on a kernel with the
NMBCLUSTERS=4096 define. This sounds suspiciously like the problem
that ...

Subject: Followup: signal 11 problem solved by yanking DDB!

just posted about signal 11's with DDB compiled in. I have also
compiled a -g /bin/sh on my system because I was getting coredumps
from /bin/sh for no apparent reason compiling some of the ports.
Since rebuilding with -g...no dumps...

My comment about -current stability stems from my relative newness
to the group, and my reading of many Emails from people say "this
dongle patch from -current" fixed up my problem...
