Six months ago, I bought a new Sandy Bridge CPU and built myself a nice desktop machine. Until now it hasn't worked...at all. I finally have gotten it working now that Oneiric is released, but it freezes every so often, making it little more than a semi-functional temptation.

What happens when the system freezes is:

• the music I have playing enters into about 5s loops.
• SSH fails
• the monitor freezes
• the mouse freezes
• the keyboard fails

The only way to fix it is to do a hard reset...and that sucks.

I'd love to at least figure out the source of the freeze so I can file a bug. I've looked in dmesg, kern.log, and the X.org logs. Nothing interesting is any of them.

Since SSH fails, I'm convinced it's not an X crash: https://wiki.ubuntu.com/X/Troubleshooting/Freeze

Anything else I can do?
