Public bug reported:
I noticed that my cpu frequency scaling was broken recently. This is
annoying because I have a 1.96Ghz and instead of being stuck at this
speed, it is stuck at minimum speed (800 Mhz).
I saw this in my dmesg (may be the problem):
ACPI Error (utglobal-0126): Unknown exception code: 0xFFFFFFFE [20070126]
[ 36.836000] ACPI Exception (video-1644): UNKNOWN_STATUS_CODE, Cant attach
device [20070126]
[ 36.836000] ACPI: Video Device [PEG] (multi-head: yes rom: no post: no)
Here is for powernowd:
[EMAIL PROTECTED]:/home/chris# /etc/init.d/powernowd restart
* Stopping powernowd: [ OK ]
* Starting powernowd...
/etc/init.d/powernowd: 156: cannot create
/sys/devices/system/cpu/cpu0//cpufreq/scaling_governor: Directory nonexistent
* CPU frequency scaling not supported
This used to work very well... I will attach my dmesg output here.
Please tell me what information I should give you.
