Yes, I bet you incurred in what's called a "interrupt storm". Asus M2N-E (and similar) had similar problems in both RELENG_6 and RELENG_7 until the end of 2006. Output of 'vmstat -i' whould prove it. You may try to alleviate it by moving PCI cards to different slots, or removing them altogether. I can't help you solving it, though :( Angelo
