Red Hat Bugzilla – Bug 438703
lost thermal monitoring after 2.6.23
Last modified: 2008-06-09 23:14:21 EDT
Description of problem: I used to have thermal monitoring available on this
machine in version 2.6.23.x. After the upgrade to 188.8.131.52-34.fc8 I've lost it.
dmesg used to show:
Mar 17 09:00:45 griffon kernel: CPU1: Thermal monitoring enabled
and there would be a running count of thermal events in
/sys/devices/system/cpu/cpu?/thermal_throttle/count but now
/sys/devices/system/cpu/cpu?/thermal_throttle no longer exists.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. upgrade from kernel 2.6.23.x to 184.108.40.206-34.fc8
No 'thermal monitoring enabled' message in dmesg and non-existent
Mar 19 09:06:02 griffon kernel: CPU1: Thermal monitoring enabled in dmesg and
Appears to not happen on i386 kernel I have on another machine.
What kind of system is having the problem? (manufacturer and model)
It's an Intel DP965LT mobo with a Core 2 Duo E6400 on it.
/sys/devices/system/cpu/cpu?/thermal_throttle is showing up once again with
kernel 220.127.116.11-92.fc8 (not sure exactly which kernel update it re-appeared in)
