Hi, I have found a workaround for this problem. Obviously there is something wrong with the way the fans are handled in this computer. I think it is the BIOS bug, which should not report 4 fans to the OS or the BIOS should handle interrupts related to fans properly???
I solved the issue by recompiling the kernel without acpi fan support. The setting is CONFIG_ACPI_FAN and I changed it from y to n. Now the kernel does not detect any fans and I think this is should not cause break something else since the computer really does not have any fans. I think that the proper solution would be to fix the BIOS. I am not an expert about BIOS and ACPI drivers, so my conclusions may be completely wrong. Regards Marko
