[Bug 321578] Re: Toshiba satellite L350/L505 fan regulation problem in Ubuntu 8.10/Ubuntu 9.10

[paul]

Is there anyone already having a solution for this? Iam able to reproduce this issue. The fan is not spinning at all when using linux, the temperature is readed out correctly. Its at normal usage, with just some internet serving going up to 70C. Once the temperature raises to 80C, the fan spin up at full RPM, however it doesnt spin down.
This is happening with a toshiba L350-168 laptop.

Core 1:      +33.0°C  (high = +100.0°C, crit = +100.0°C)  

(Note, these values are just after the temperature hit 80C, so the fan
is spinning at full speed at this moment. )

Iam not sure what exactly the cause is, however, iam unable to load the toshiba_acpi module. It errors out with the next error:
paul at paul-laptop:~$ sudo modprobe toshiba_acpi
[sudo] password for paul: 
FATAL: Error inserting toshiba_acpi (/lib/modules/2.6.31-20-core2/kernel/drivers/platform/x86/toshiba_acpi.ko): No such device

This means iam unable to use the toshset functions as the required kernel module isnt loaded: 
paul at paul-laptop:~$ toshset 
required kernel toshiba support not enabled.
paul at paul-laptop:~$ fan
fan: laptop does not have cooling fan or kernel module not installed.
paul at paul-laptop:~$ 

If someone needs some more info, let me know.

Paul
