I've had the same issue with my TravelMate 4404WLMi with a Turion ML-34 processor. Dapper worked fine, both x86 and amd64, while I had to run Edgy amd64 with scaling_max_frequency bolted to 800000 to prevent overheating. Turned out that polling was disabled. After setting the TZS0/polling_frequency to 1 second, things started working, ondemand scheduler now knows about CPU temperature and I have no need for powernowd.
I wonder why polling wasn't enabled in the first place. -- laptop overheats when performing CPU intensive tasks. https://launchpad.net/bugs/22336 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
