I've seen it too, with a 4.5 system with a maxtor drive. Unfortunately, I've never been able to track it down to anything certain: I was (and still am) leaning towards poor hardware over an OS fault. The only thing leading me to believe it's NOT a hardware issue is that the kernel seems to be running, although nothing responds: network activity lights flash on the NIC and switch, but NOTHING else works (have to powercycle). I remember someone else pointing out the same problem about a year ago, and nobody ever offered any explanation of the problem or even hinted at a solution.
