kernel:protection fault trap, code=0
Stopped in pid 8.1 (sysctl) at amap_wipeout+0x82:  movl 0(%r13),%esi


Beyond that:

uvm_unmap_detach()+0x45
uvmspace_free()+0xe4
exit1()+0x236
sys_exit()+0x67
syscall()+0xa9

When I typed 'reboot 0x101', it did dump; however, it didn't reboot.
And I can't do anything useful with the dump; savecore says "/dev/wd0b:
device busy"...
