I use two 125MHz/256kB HyperSPARCs with -current and lately the rmind- 
uvmplock branch.

I've seen that.

I haven't seen any SCSI errors at all, and no panics lately. What I  
usually get is a watchdog reset.
Also, for some weird reason my SS20 keeps going for a LOT longer when  
booted cold - I confirmed this several times ( when warm booted I'd  
get a watchdog reset within minutes running build.sh, cold booted the  
same kernel kept going for more than 30 hours with load avg. >4 ) but  
I don't have the faintest idea what could cause that.
For the records, I have the OS, $OBJDIR etc. on local disks, sources  
over nfs.

have fun
Michael
