So, this was ironic. I’ve been having trouble with Edgy ever since I installed it. In particular, my CPU will hang and get very hot, eventually causing my computer to automatically shut down. Following a conversation on IRC, I decided to see if a fresh install of Ubuntu would fix my problems. So, I downloaded and burnt an Edgy CD, then installed it. I keep /home on a separate partition, so I didn’t lose anything important. Once I got back into Edgy, I started rebuilding some of the packages that I had custom-built on my previous installation. After the CPU had been runnning at nearly full speed for a couple of hours, I remarked on IRC:
hey, this fresh install seems to have fixed my cpu problems *knock on wood*
I pressed enter. I saw the words appear on my screen. Then the entire screen went black, and I was greeted with:
CPU critical temperature reached (92° C) Shutting down…
So, I guess the moral here is, when you’ve solved a problem, don’t let your computer know you’ve fixed it.
Just wanted to let you know that this seems to be a more systemic issue. I’m attempting to track down what’s _really_ going on. I have Kubuntu (running fluxbox) on an IBM Z61p. When I use the default vesa driver for my ATI Mobility FireGL V5200, M56GL, 71C4 graphics card the performance is horrible, but the machine runs just fine. When I try the Xorg ati (radeon) driver, I get nothing on the display at all. When I try the latest fglrx from AMD (ATI) [ v8.32.5-1 ], it loads with DRI and all the goodness it should, but at some random point, my system will crash with:
Message from syslogd@isohel at Wed Feb 14 13:38:39 2007 …
isohel kernel: [17179814.032000] Critical temperature reached (128 C), shutting down.

The system is going down for power-off NOW!
None of my thermals are that high. I was running an acpi -V to a file at the time and my processor temps just before this were a mere 45 C.
Anyway, I’ve been digging into this one and have come to find that many people have encountered this, but I’m not sure how many of them are running fglrx. Are you?
I’m not, I’m using the radeon driver
