Comment 199 for bug 22336

Hi i did post something about my now-almost-defunct laptop which was overheating. CPU was a pentium-m. in fact, it was overheating on feisty if i remember while previously (before an upgrade or update) it did not. I also strangly noticed that, at some point, the hard drive would lock and stop spinning- a feature that was not present on the actual machine- in fact the hard drive was heating so much that it was actually crashing -or call that a panic :P - . Since the PC had almost not the time to boot before to smell like something burning and crashing, i stopped using it. Recently i discovered that the hard drive was in fact intact and not overheating -through ide/usb interface- on a "good" system running the same version of ubuntu. More recently i decided to boot ubuntu from livecd on the "dead" machine. Didnt overheat, even when i wanted it to. i then plugged my hard drive to the usb port, installed ubuntu on it, updated.... No crash, no heat, nothing. My point is: i dont know if its kernel-package related, but somehow something blew my ide contoller up, or more likely has been driving my chipset crazy, the chipset running everything else -CPU ?- crazy as well. i recall that the cpu was changing its frequency all the time very fast (trusting the gnome applet). The thing that controls this is probably in the chipset (but i dont know :O ), and, is probably controlled by some sort of basic kernel driver or ACPI. Something overrides the normal, natural, BIOS-defined way of keeping the computer safe, or lies to the bios, or hte bios doesnt detect this stuff as an error and does its usual job driving the rest of the system crazy, making the box crash.
