netbsd-current kernel crash

[6bone%6bone.informatik.uni-leipzig.de@localhost]

hello,

my kernel crashed with:

fatal page fault in supervisor mode
trap type 6 code 0 rip 0 cs 8 rflags 10246 cr2  0 cpl 6 rsp 
ffff800069a29b90
kernel: page fault trap, code=0
Stopped in pid 0.3 (system) at  0:      invalid address

Any Ideas what could be the problem?
