I have been using ubuntu 11.04 beta for the past two months... I needed to use it because of the repositories/extensions exclusive to that build.

Every so often however (sometimes every few hours, sometimes every few weeks) it will randomly shut down.

At first I thought it had to do with the mild overclocking I had in place. So I removed it.

Everything was fine for a few weeks, and I just woke up to it being off again. Quite annoying!

Anybody know what could be the cause?

  • What is in the syslog leading up to the shutdown. Is there any kernel dumps, are any errors logged?

Have you checked the heat in your hardware? Is it all cleaned up?

Before installing 11.04, was your hardware running ok? If so, I suggest you to downgrade (or reinstall) 10.10, and build the packages you need by hand. You can look for PPAs also.

Is this question for real?

You're seriously asking if beta code on an overclocked machine might be less stable than you'd expected, on a Q&A site for pro sysadmins?

Let's assume you're being serious, the answer would be; yes, I'd not expect that much stability, have you tried losing the overclocking and/or contributing to their dev efforts via a bug report?

Like you say, quite annoying!
