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?
Your kernel seems to do the trick here - thanks!
