Great, I *love* responding to my own emails. Anyway, the non-SMP kernel went
bang the same fashion the SMP one did, it only took longer. So I went back to
the SMP kernel with debug info. Which means that I now have a stack trace (see
below). What happened is fairly obvious - the ISDN card's interrupt handler
got a bad sc pointer, tried to dereference it and the whole system didn't like
it. Of course the interesting bit is to find out why...
I'll keep the dump around for some time in case someone wants a specific view
of it but I'd rather not upload it to a publicly accessible place. It's 256MB
in size...
TIA,
Timo
Anyway, here's the panic message:
