Just had my CPU pull a thermal overload shutdown, Ubuntu Lucid upgraded 31.5.10 Gigabyte GA-MA785*** + AMD PhenomII 550BE (quadded) - no issues with this setup with various Debian based distros until today.
1st indication of problem when scaling app reverted to performance instead of ondemand, then post fglrx manual install using sgfxi - desktop reported scaling problem. Shutdown pc just in time - cpu temp too high to reboot for ~15mins!! kern.log:>> powernow-k8: Found 1 AMD Engineering Sample processors (4 cpu cores) (version 2.20.00) May 31 15:35:28 P***** kernel: [ 0.941662] [Firmware Bug]: powernow-k8: No compatible ACPI _PSS objects found.
