Re: Current Kernel does not boot



I had the same problem with stable. The panic was gone when using -O2, in 
complete:

 COPTS+=-O2 -mcpu=21164a -pipe

does work for me, with the -O2 being important. -Os does work, too, -O0 (or 
none -O Option at all) did not  work and produced a trap, though it paniced 
at a different stage. 
Was a topic in here a couple of weeks ago, too. Did not recheck, but maybe 
Problem Report 34446 is of interest.
