Hello,

I have an SS20 with a pair of 125MHz/256kB HyperSPARCs. It manages to  
build its own kernel with -j4 just fine, it even finishes build.sh -j4  
tools but a few hours into build.sh -j4 distribution still make it  
fall over.
It takes a lot longer than two weeks ago to make it fall over though.

Here's the trace:
kernel: alignment fault trap
