Re: SMP support for sparc64 is now in -current

[Chris Ross <cross%distal.com@localhost>]

  Okay.  I built current as of this afternoon, and tried bringing it  
up on a dual-200Mhz UltraSPARC Ultra2 (yes, that's with UltraSPARC-1  
processors).  Network boot, NFS root and swap.

  It got to the end of the "boot to multiuser" process, but before  
running getty, crashed:

Starting inetd.
Starting cron.

  Any other information I can provide that would be useful?
