| I'm running an ultra 1:
|    Sun Ultra 1 SBus (UltraSPARC 167MHz), No Keyboard
|    OpenBoot 3.1, 128 MB memory installed 
|
| Using the 1.5ZA snapshot, while trying to rebuild the kernel, I get
| the following kernel panic.  I grabbed a trace.  
|
| First, is this a known issue?  Second, if its not a known issue, can
| someone give me some general direction on what to do, or where to 
| look to figure out more about the problem.  I've tried it several
| times, and the problem is reproducable.  Also, if I run the compile
| with -pipe, it general completes more of the compile than without.

Make sure block_disable is set.  Boot with -d, and when you
drop in to ddb do `w block_disable 1' and then `c' to continue.
