I think i got the problem: I made some test. The problem is the module radeonfb. If i compile radeonfb as a module there is no problem with the fan control. But if i compile it into the kernel, than fan control will be destroyed and the fan doesn't stop working from the beginning of the system start. The other modules (fglrx, agp_gart) have no influence to the fan behaviour. - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
