So does anyone with or without SMP on powerpc see deadlocks since

Frank mentioned a few days ago he was getting deadlocks on Pegasos II.

Those deadlocks are definitely Pegasos-viaide related. The MorphOS team
confirmed that they had to implement a workaround for the problem.

It is easy to reproduce. Just read files from a disk at channel 1 and
another disk (or CDROM) at channel 2 at once. The system will lock up after
a few seconds.

Ok, that's definitely unrelated - there's not a single VIA chip in my G4 ;)

Anyway, I found out by accident ( didn't build a DIAGNOSTIC kernel for a while ) that IPIs tend to time out occasionally, that may be the real root of the problem. I'll look into that when the G4 finished its fsck dance - it's really time we get journalling ffs.

have fun
Michael
