[Bug 22336] Re: CPU overheats during high usage "throttling <not supported>"

[edward stroupe]

processor is presently running @ 50% plus - with just system moniter open, recently started doing this when opening yahoo e-mail account. Did this with Windows XP, but nit with Ubuntu @ early install and until just a few days ago. When running video clips near
HD, off line, fan turns on. Use an under pad with 2-fans to add cooling plus a side desk fan. 2004 Dell model I-5150. The 'Van Halen
of computers?! Ed.

Bug description:
  I can't compile anything larger than ndiswrapper. I couldn't even produce a
  backtrace for gthum. I can't play tuxracer either. My laptop overheats while
  running linux, and is powered off by kernel:
  Sep 23 12:21:20 localhost kernel: [  728.519975] Critical temperature reached
  (80 C), shutting down.

  I must stress that this issue doesn't occur while running WinXP x64 edition. I
  ran CPU Burn-in for 7 min without any problems while it takes only 3min on linux...
  I can play games for say half an hour (since later I just lose any interest).

  My hardware is: Acer Aspire 1522WLMi (AMD64 3000+).
  /etc/modules contains powernow-k8, and cpufreq_userspace.
  I haven't tried any other distro on this laptop properly so I can't confirm if
  it is ubuntu specific.
