So basically you have all debugging disabled... OK, I tested it this
way too and no go. Still almost instant trap/panic/reboot when trying
to write into null mounted directory, and, sometimes even just reading
it shows similar behavior.

I am using freshly csup'ped sources for every build, 10-CURRENT. In my
case, nullfs is loaded as module, too, so if you could really use null
mounted directory to work with, there is some other difference between
us...

In my case, command sequence

mount_nullfs /data/src10 /usr/src
csup /usr/share/examples/cvsup/standard-supfile

yields almost immediate panic, reproducible 100 %.
