crash on amd64

Hi,

while cross-building tools for i386 on amd64 running a kernel
compiled from sources cvs update an hour or so ago I got the
following:

uvm_fault(0xffff800059c3edc8, 0x4002000, 2) -> e
fatal page fault in supervisor mode
trap type 6 code 2 rip ffffffff8023867a cs 8 rflags 10286 cr2  4002220 cpl 7

Is this a know problem or something new? This is on 2 Dual-Core Opteron
machine btw.
