I can't tell whether this is related or not, but the timing is making me
suspicious. Today during `make build', my computer locked up hard ... no
ddb, it just froze. I can't remember if or when something like that
happened on this box before ... I am used to a non-crashing box despite
hours and days of compiling things. As you can see in the attached
dmesg, I am following -current via source successfully for a while now
(IIRC my last reinstalll was shortly after the switch to X.org, so you
can estimate how often I put this box to work with rebuilding OBSD and
making releases.)

The dmesg is from the 2 days old kernel I reverted to after the crash.
During my make build'ing, I was running a GENERIC kernel with the
MAX_KMAPENT change mentioned above, of course.
