In F15 -alpha, the thinkpad_acpi module does not create /proc/acpi/ibm/ecdump anymore. The log files don't tell me why... This file is needed however by tpfancontrol. which now fails with tp-fancontrol: line 242: /proc/acpi/ibm/ecdump: No such file or directory Can one get it back? uname -a Linux t61p 2.6.38-0.rc8.git0.1.fc15.i686.PAE #1 SMP Tue Mar 8 08:16:43 UTC 2011 i686 i686 i386 GNU/Linux
I don't think the upstream kernel is going to change back. Assigning to kernel in any case. Where did you get 'tp-fancontrol' from? It's not something we ship in Fedora (as far as I can tell), so it's not something we can fix.
Your best bet is likely to report this to where you got 'tp-fancontrol' from, so they can fix their code. In any case the kernel should be providing the optimum fan control automatically wherever possible.
We don't provide tp-fancontrol
The /proc/acpi/ibm/ecdump file is created when the option experimental=1 is given to the thinkpad_acpi module; tp-fancontrol also needs fan_control=1 option. To allow tp-fancontrol to work with Fedora 15 you should create a modprobe config file in /etc/modprobe.d with the following lines: #Options to thinkpad-acpi to allow tp-fancontrol to work. options thinkpad-acpi fan_control=1 experimental=1 e.g. cat /etc/modprove.d/tp-fancontrol.conf #Options to thinkpad-acpi to allow tp-fancontrol to work. options thinkpad-acpi fan_control=1 experimental=1 Reboot and tp-fancontrol should work now. If you only need manual control of the fan, e.g. 'echo level 7 > /proc/acpi/ibm/fan' Then only fan_control=1 is required. Hope this helps.
