sparc64 5.1_RC1 crashes

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

 Twice this evening, while building packages from pkgsrc, I've had  
the following two panics (at the same place) on my Quad-processor  
E420R, which is using raidframe to RAID1 it's two scsi disk drives:

 This is a custom kernel, but I do have a netbsd.gdb to run against  
it.  I think my /var/crash is full, so I'll have to fix that when it  
comes back up, but.

 Anyone have any suggestions as to how to diagnose this one?

 Thanks...
