When I try to shutdown ubuntu, with increasing frequency it gets stuck on a screen filled with text ending in [endtrace0xHEXCODE].

This happens when I use commands to turn off the computer as well. I looked it up and it seems like the problem could either be an ongoing kernel bug or a video driver issue.

What gives? How do I get my computer to shut all the way down every single time?

I use Ubuntu 11.04.

Are you using restricted drivers? – skub Jan 21 '12 at 2:43
I use Broadcom wireless and ATI Radean graphics. – A. Hayes Jan 21 '12 at 21:12
