Can you send me > a copy of the DSDT table (/sys/firmware/acpi/tables/DSDT)? Oops, I hadn't noticed that! In fact, that fan speed is usually read correctly, but intermittently jumps to some absurd value. I don't think it's a problem of the driver, since I see this in the BIOS "system info" screen as well. Here's an example of the usual output: atk0110-acpi-0 Adapter: ACPI interface Vcore Voltage: +1.27 V (min =3D +0.80 V, max =3D +1.60 V) +3.3V Voltage: +3.29 V (min =3D +2.97 V, max =3D +3.63 V) +5V Voltage: +4.93 V (min =3D +4.50 V, max =3D +5.50 V) +12V Voltage: +12.00 V (min =3D +10.20 V, max =3D +13.80 V) CPU Fan Speed: 1562 RPM (min =3D 600 RPM) Chassis Fan Speed: 0 RPM (min =3D 600 RPM) Power Fan Speed: 1216 RPM (min =3D 600 RPM) CPU Temperature: +42.0=B0C (high =3D +60.0=B0C, crit =3D +95.0=B0C) =20 MB Temperature: +29.0=B0C (high =3D +45.0=B0C, crit =3D +75.0=B0C) =20 For the moment I've disconnected the chassis fan because it was very distracting. If it's of any interest, I've put a copy of the DSDT table here: http://users.uoa.gr/~adia/DSDT Thanks!
