This works fine with a single processor kernel, but the module fails to load with a kernel compiled for SMP. I gather this is true for all the Isdn4Linux drivers, though as I have a three processor machine, this is a real pain ! Advice seems to be to get an external TA of some kind, but that would seem likely to add to ping times, and maybe to create a bottleneck if I ever get 128k or compression to my ISP ! So, two questions: 1) are there any fixes for this problem in the pipeline and if not, 2) how easy would it be for the kernel novice to adapt a uniprocessor driver to survive in the SMP environment ?
