[solved] thinkpad_acpi: cannot load module

Question

Hi, I can´t modprobe the thinkpad_acpi module on my x61, I get the error below:
FATAL: Error inserting thinkpad_acpi (/lib/modules/2.6.34-ARCH/kernel/drivers/platform/x86/thinkpad_acpi.ko): No such device
Although there is a thinkpad_acpi.ko in this directory.
Any suggestions? Sorry for this short discription, but the output is simple and maybe the solution just as well. :-)

Answer 1

I'm no expert on how the module reads the system info (from proc or sys perhaps?), but for whatever reason some ThinkPads just aren't detected properly. The force_load option is specifically for this case with thinkpad_acpi ('modinfo thinkpad_acpi' for details).
If using force_load bothers you, you could try updating your BIOS to the latest version. That might fix the detection problems with Linux and thinkpad_acpi.
As I tend to forget to do this, you may want to configure the option to be persistent by adding it to modprobe.conf.
Edit: Forgot to mention, I tend to run into forgetting to rebuild tp_smapi after kernel rebuilds. I was too quick to reply before realizing that thinkpad_acpi != tp_smapi.
