Hi --
I have an HP z600 workstation that has the FAN running full when idle. In fact, after the boot, the fan never slows down or varies. I looked in dmesg, and noticed this:
[ 1.516778] ACPI Error (dsfield-0143): [CAPD] Namespace lookup failure, AE_ALREADY_EXISTS

Anyone know what could be done to fix this?
