Comment 199 for bug 524281

I think I had the same problem on a Dell Latitude E4300 (Core 2/P9300) and the interesting thing was that the overload happened mostly when the laptop was being charged and when I removed the AC adapter to run on battery, after some minutes, the laptop was responsible again. In my case, when this bug happened, the whole laptop was not flawless any more, very slow and high CPU load. There is an other problem that the laptop shits on the cpu scaling policy and decides about the current speed without any sane reasons. If this bug happened and the cpu scaling dropped the frequency to 800 Mhz, the laptop was quite useless when it was being charged.

I think I experienced the bug under Maverick first and the upgrade to Natty did not help. Now I upgraded to the latest unofficial natty kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.39-rc4-natty/ and the intel graphics driver from this PPA: https://launchpad.net/~glasen/+archive/intel-driver and after one day of use, the problems seem to be solved expect the cpu scaling crazyness, but I do not have too much hope that a linux will ever work on this laptop without problems.
