>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.

 This problems even happens if I boot the machine into single user mode
 and shut it down before mounting any filesystems.

 This looks like a random fault observed by a few people since the MP changes
 for cpu  initialization on sparc64 have been merged - can you realy reproduce
 it with shutdown on your machine? That would be realy helpfull ;-)

 Yes, with 100% reliability.

 It seems that Matthew Green's latest changes fixed the problem. Both
 "shutdown -r" and "shutdown -p" now works withouth problems for me.
 This PR can therefore be closed.
