To fix, start with setting hw.pci.do_powerstate="0" in /boot/loader.conf, and rebooting. If this fails check your BIOS version for both the main system and the RAID controller (my case a Dell PERC 3/Di). Both were factory shipped BIOSs: Main BIOS: A01 RAID BIOS: 2.50 SMC BIOSs: 5.78/1.23 Upgrading the BIOSs to: Main BIOS: A07 RAID BIOS: 2.80 SMC BIOSs: 5.87/1.32 Fixed the issue. BIOS notes show that around A03/A04 there was a fix implemented to resolve spurious and false NMI errors. Additional Info: Dell don't have it in the BIOS notes, update in the following order using floppy boot/BIOS disks: System Management Card and Backplane. Main (System) BIOS **Reboot** RAID BIOS **Reboot** Regards, -- Matthew Sullivan IT Security Manager The University of Canberra A member of the Australian Association for the Abolition of Acronym Abuse, Regional Group Headquarters, Strategic and Tactical Operations Planning (AAAAARGHSTOP).
