Going back to the old ALSA tree from 2.6.2 'solves' the problem. I am
not experiencing the gstreamer lock, nor the interuptions in other
programs' playout.

Regarding the nforce interupts problem you mention, I only get it when
APIC is turned on, which is not the case here.
                                                                                
Tell me if I can provide more information,
thanks,
