Hello.
My CPU FAN is always at 100%, even if my CPU usage is near to 0-1%.
For example, now, my CPU work at 4%, the CPU temperature detected is 36°Celsius, but the FAN is always so noisy at 100% !
I don't know if this bug is hardware specific, so I give you my configuration :
Kubuntu Maverick beta
AMD PHENOM II 1090T (x6)
ASUS CROSSHAIR IV Formula
8GB DDR3
BIOS : Cool'n'Quiet is activated (but i tested with this option off, and the problem still the same)
Thank You very much
[EDIT]
I found on some forums that it could come from acpi drivers. Some users succeeded to have it working by modifying /etc/default/grub file. They had to add this line :
GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"
For me it didn't work. When I rebooted, it was not better, and I got some KDE errors, and Wifi didn't work anymore.
So, I removed this line.
I give you the result from sensors command :

What is strange, is that I don't get any Fanspeed information.
And dmesg gave me this information :
