>Description:
After I upgraded my ULTRA60 from a few weeks old 4.99.2 to 4.99.3 its
kernel started crashing if I try to powerdown or reboot the machine
via the "shutdown" command. Here is the backtrace provided by
the kernel debugger:

syncing disks... cpu0: data fault: pc=1232014 addr=1b000000
kernel trap 30: data access exception
Stopped in pid 813.1 (reboot) at        netbsd:buf_syncwait+0x74:       ld              [%l0 + 0x14], %g1

I tried to get a dump with "reboot 0x100" but it didn't work.
