cat /proc/i8k

and dmesg after modprobe i8k shows:

i8k: unable to get SMM BIOS version

Additionaly using this module enabled on my laptop dell E6510 causes weird usb problems: after boot up dmesg says: nobody cared (try booting with the "irqpoll" option)and mouse after a few cursor moves stops working.....

Hello!

Please, could you post 'i8kctl temp' here.

Also, try 'i8kfan - 2' and to see if fan switch to max speed even it is for a few seconds.
