Indeed. I didn't have problems with dual PPro200, but after I did
upgrade it to dual P-III-750, it does hang up. Machines have
128 MB, and 750 MB memory, respectively. (Disks and host controller
were moved over.)
I recall having ran same earlier PPro optimized 2.4 kernel on PPro200,
and on P-III (2.4.6-ac1, or 2.4.10). It hung up too, which prompted
research on kernel versions.
This all does point to some sort of deadlock window somewhere.
It appears to be practically untriggerable with PPro200, but
trivial to hit with P-III-750.
Now to have a reliable way to find where the CPUs are spinning
when the thing does not work... (I have tested kdb: keyboard
dies at hangup -> kdb becomes non-functional...)
