| |
2.6.34-stable review patch. If anyone has any objections, please let us know.
------------------
From: Andreas Herrmann <andreas.herrmann3@amd.com>
commit d535bad90dad4eb42ec6528043fcfb53627d4f89 upstream.
Reported temperature for ASB1 CPUs is too high. Add ASB1 CPU revisions (these are also non-desktop variants) to the list of CPUs for which the temperature fixup is not required.
Example: (from LENOVO ThinkPad Edge 13, 01972NG, system was idle)
Current kernel reports
$ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +74.0 C Core0 Temp: +70.0 C Core1 Temp: +69.0 C Core1 Temp: +70.0 C
With this patch I have
$ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +54.0 C Core0 Temp: +51.0 C Core1 Temp: +48.0 C Core1 Temp: +49.0 C
