RE: BETA6.0 - AMD Opetron 6272 (16 core) multiprocessor config crashes
Finally got this to work.. Although not sure if this is still related to
irq on driver issues on the network card..
But I was able to insert a PCI express network card and got this going ..
The issues still stays if I use both ports on the dual network card.. i.e
to make this work I had to configure one network on the motherboard and
the other on the pciexpress network card.. the server crashes if I use
both nics on the motherboard or the pciexpress network card..

Does it hang immediatly after enabling the second nic, or some time later
? if you can enter ddb, does 'show events' report interrupts for this nic

It looks like an interrupt routing issue. I'm not an expert in this area;
a PR with the dmesg and ACPI infos would probably be the best way to get
