Dear Paul, I am glad to see some significant progress on this bug. I guess you refered to me in your post... Yes, I have been running openSUSE 10.0-2 AMD64 for about 2 years now. I have had only 2 shutdowns over that time with typically heavy machine load. openSUSE uses <B>ondemand</B> governor by default. I am sure you are all familiar with the concept of this pm utility. In essence when the temperature reaches a trigger point CPU is scaled down and system cools down a few degrees, then resumes at full power, etc.

So having ondemand working cleanly is critical at least on Acer Aspire 1520 series. Performance governor kills SUSE instantly for example. Same goes with userspace. In other developments my laptop is showing some "great" hot results. I was hoping to convert my c: vfat drive to ntfs but it overheated just a mere 2 minutes into the operation (I had to restart into some special safe mode for that). Windows install cd in recovery mode overheats nearly instantly. Surprisingly I was able to complete both XP x32 and x64 setup w/o any problems in the past. Maybe they load an AMD driver by some chance... System simply locks up if left in BIOS setup for a couple minutes. And yes, it is possible use it to fry an egg! -- Laptop overheats during high CPU "throttling <not supported>" https://launchpad.net/bugs/22336 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
