quad 604 SMP update

quad 604 SMP update

[Taylor Holliday]

Started removing DIMMS - and the machine booted :-).

Any idea why total bogomips would say 11.96 when it should be 1196?

Mark is having the same issue, I'll look into it.

Note that the DIMMs might or might not be the reason of the problem.
Please tell me what PCI hardware you have in the box (and also, try with
other DIMMs...)

Ben.

This was introduced between test12 (or test9?) and current 2.4.0.
I have 2996 <-> 29.96.

I don't have a quad CPU machine, but my 7600 when upgraded to a dual 200MHz
board had similar trouble. It has trouble booting Linux if I have all of
the memory I have in it, or in the wrong places. However, the MacOS can
use both CPUs fine with any configuration I try. I have no PCI cards in
this machine, so that isn't the problem for me. Incidentally, the DIMMS
I have to remove are the ones Apple shipped in it.
