NetBSD 6.0_RC1 (MORR) #0: Sat Sep  1 19:08:25 CEST 2012 sh@bespin.stars:/home/sh/sysbuild/netbsd-6/amd64/obj/usr/src/netbsd-6/src/sys/arch/amd64/compile/MORR
>Description:
After upgrade from 5.1_STABLE to 6.0_RC1 after some time (4-9 days) router dies with this panic:

uvm_fault(0xffffffff80e61d20, 0x0, 1) -> e
fatal page fault in supervisor mode
trap type 6 code 0 rip ffffffff80607a93 cs 8 rflags 10246 cr2 48 cpl 4 rsp fffffe800784bb98
kernel: page fault trap, code=0
Stopped in pid 0.64 (system) at netbsd:pf_state_tree_id_RB_REMOVE_COLOR+0xcc:c
mpl $0x1,48(%rax)

I've updated now system to RC2 and will see if it happens there. 
5.1_STABLE was working fine on this computer.
>How-To-Repeat:
Wait for it.
>Fix:
None.
