2.6.27 and pci=nomsi did not help stability. For the record, after I changed the motherboard to a MSI K9A2GM-FIH (but kept same RAM/cpu/disk/power supply/case) I successfully stress tested the machine for 10 days without any issue on 2.6.27 intrepid kernel (without specific boot option).
Conclusion: both ASUS M3A32 MVP Deluxe wifi and ASUS M2A-VM likely doesn't support properly some phenom processors even with latest BIOS (the same boards are stable with Athlon X2). -- Phenom kernel 2.6.24-8-server BUG: soft lockup - CPU#3 stuck for 11s!
