I've spent some time investigating the problem with the hanging

The cx88 doesn't seem to like my system running with two passive ISDN
cards (software PBX) causing a significant IRQ load. After I disable
the cards the reception works quite stable.

I'm not sure how to resolve this issue... The system is fast enough
(3600 Bogos) to handle that load.

Any idea?
