Hi,

just got this crash on an oldish Ultra2. Kernel -ajusted to the available
hardware and needed features- compiled from sources cvs update'd an hour or
so ago. The system crashed while trying to compile a new userland.
Src- and objdirs are come over nfs. The crash is easily reproduceable by just
calling build.sh.  Kernel from Tue Oct  3 19:38:04 MEST 2006 works fine...
