[Bug 370173] Re: Ubuntu 9.04 laptop overheat and shutdown

[ceg]

** Description changed:

  Ubuntu 9.04, fresh install on Acer Aspire 5005.
+ (confirmed also with 9.10)
+ 
  Not sure about package, but it seems the problem is with CPU frequency adjustment or fan control.
  Laptop shuts down right in the middle of CPU-greedy operation overheated. I haven't seen it before (since 7.10).
- The issue is discussed at several forums (eg. http://ubuntuforums.org/showthread.php?t=1130450)
