hi,

i checked out cvs again, this time on the Power Mac running 2.99.9 on  
2.99.10 userland.

booting a G4 optimized kernel (-mcpu=7400, -maltivec) fails with  
following messages (copied manually):

trap: pid 3.1 (atabus 1) kernel MCHK trap @ 0x54bfb4 (SRR1=0x2041020)

trap type f00 at 3c3568

(and so on and so forth)

booting a not-optimized kernel stops also in the same trap, but lists  
only a few lines more; the optimized one spits out more.

a 2.99.9 kernel from october 5th runs fine.

dmesg:
