Hi

Also: Has s.th. changed in respect to the modules. I have one module wich
goes on an endless interrupt loop freezing the device. The driver works
fine for 3.0  - 3.4 preempt rt kernels? This is a miscdev based driver. If
someone is interested i can post the source over here. But unfortunatly i
have not figured out why this thing goes to an endless interrupt. The
identical driver works flawless on 3.4.

I have just crosschecked with 3.6.9. The same error as with the preempt rt 
version. So it's not an preempt rt problem.

Best regards
Tim
