Oversleeping Core

This morning I powered up, as I usually do, and went to make a cuppa. Came back an looked at the black screen.

After a couple of goes,b I rebooted to recovery, and spotted an error about failing to wake a core up, "failed to wake cpu #3". Sure enough, my own conky cpu monitor confirmed only three cores were there (out of 4).

Rebooted and went to the BIOS. I didn't actually change anything, but I resaved, and everything worked just peachy again. Power on tonight, no problem. Should I be worried about my CPU, or is this just a glitch?

For info, AMD 965 BE quad, Gigabyte MB.

Re: Oversleeping Core

I once had this, I had to take out the BIOS battery for a full reset. Hadn't had the problem for the rest of the machine's life cycle anymore. I'd file this under isolated incident.

Re: Oversleeping Core

That's reassuring, and there's been no problem since. I think maybe one of the cores had been out drinking and was just a bit under the weather. Learned its' lesson now and going tea total.
