Patch fixing the problem

Ok, here's a patch to fix the problem.

The problem was that the driver didn't clear all interrupts in the 
chip before enabling interrupts and on my laptop it ended up taking
the interrupt long before the driver was ready to handle it.

Would you mind giving these kernels a quick test?

Comment 4 Jes Sorensen 2007-10-29 11:06:31 EDT
Your kernel seems to do the trick here - thanks!
