With nmi_watchdog=1 we see in kern.log "APIC error" but the machine stayed stable during 3 days of stress testing: ...

Then we'll go back to testing the ASUS M3A32-MVP Deluxe/WiFi-AP with the newer 1002 BIOS also released on 20080331. Note: for msr decoding xxd should be used since hexdump doesn't work: xxd -s 0xc0010015 -l 8 /dev/cpu/0/msr So people having stability problems with Phenom 9x00 with Linux should try nmi_watchdog=1 as boot option.
