Comment 106 for bug 220706

ASUS Mb Nvidia chipset also. Device in question is part of a SATA software raid, and seems to fail intermittently. Hard to rule out actual hardware failure here . . .

This machine reboots strangely, and also features a Pioneer DVD drive I've seen mentioned, but it is not the failing device . . .

(recover the raid after previous problem with this)

I will have more specific hardware specs after getting to office to had reboot it. Is this related?
