I can't reload a kernel module for trying new flags.
thinkpad_acpi default is without
fan_control=1. So if my computer runs really hot and the fans don't go to full speed it might sometimes be usable to just temporary load the module with
fan_control and set the fan for a several minutes to the highest possible speed and change everything back to normal afterwords.
This isn't possible because it seems that some kernel modules depend to others and it seems that modern Linux kernels are checking that.
So what did I do so far:
- Checking the dependencies
modinfo -F depends thinkpad_acpi
- Try to unload these modules
modprobe -r $dependencies
- Some modules depend again to others, try to unload them too. Doesn't work, even if there are no 'dependencies' (or at least modinfo tells me that)
- Google a lot for
modprobe: FATAL: Module x is in use.
- Reading tldp
