Hi Rob,
If I'm running any kind of power management it's not intentionally.
Anything I know about power management and Linux (or Windows) I learned
in the last few days - it's always been a topic I've been happy to
ignore. I swear I didn't deliberately touch anything to do with power
management until after the problem appeared.
Actually, as a side note, I don't even have anything under the directory
/sys/devices/system/cpu/cpu0 except topology, so a lot of the stuff
people are talking about above can't be applicable to me.
I did clean out my fan and it is running better now. I reinstalled
Ubuntu successfully and I am having no problems now. Of course, I also
have not allowed the battery to fully charge yet to try and test my
theory again. But the problem came and went away in a fashion that could
not have anything to do with anything I had installed, or any problem
with my fan - I was still having the problem trying to use the LiveCD
(system stopping under what could never be called an excessive load,
just starting Firefox would do it), and it went away when I allowed my
battery to drain a little, again running from the LiveCD. I can't think
of any good explanation for this. It seems like the battery is fully
charged but I have a battery icon rather than a cord icon in Gnome,
FWIW.
The fan is speeding up and slowing down with load just like I was used
to it doing on Windows - maybe my BIOS is taking care of this?
Here is my output from acpitool -e with a fair number of things running:
