OK. So I'm late to this thread. But is everyone _sure_ hardware isn't a problem? Yes, turning SMP off solves it, but that also reduces 5 V power consumption by 3-5 Amps (not-oc, normal load).
FWIW, I have an Abit BP6 with only one UDMA33 disk. No hot video card. I'm stable at 2 * 5.5 * 98 MHz even under heavy load from my `cpuburn` tester. I can also run at least four instances of
dd if=/dev/hda4 of=/dev/null bs=1024 &
Without causing ANY lockup. I can thrash the head actuators by changing hda4 to hda1 for few of them. Still no trouble. Of course, I use short cables for UDMA33. 2.2.13 SMP.
But I have a 300W power supply, and it still sags 0.20 V. The original poster had 12 disks in his box. Multiple powersupplies, I hope. Was a voltage check done (lm-sensors)?
OTOH, the BP6 may have some problems freeing some IRQ's. Perhaps the newly released BIOS will help.
