Which ps2 utility did you use and what did you arrange your IRQs to be 
set at.?

Are you using a IBM thinkpad 600e or another laptop. If so which model? 
If you are using the 600e would please post the following information:
What you set your IRQs at with the PS2 utility?
The results of uname -r
A copy of your kernel.
A copy of your device.hints.
A copy of your dmesg.
A copy of any customizing you have done to your /usr/src/ files.

This seems somewhat encouraging, I hope it can solve my problem with the 
interrupt storm. I get that one solved I will go onto other issues.
