Sorry for that stupid mistake.
The patches to the isdn part do not make a difference to the kernel hang
that i experienced lately.
When i reversed the patch for the mentioned files i checked the kernel
configuration and noticed that the "diversion services for isdn" where
on, a feature that i cannot use at the moment with my carrier.
I switched them off before i compiled the new kernel.
This is what makes the difference.
Kernel 2.4.0-test13-pre4 was the previous one that I used (with
diversion services on, i am a fan of make oldconfig) and that did not
show the problem (as all of the previous kernels, test9, test10, test12).
I have reversed the patches part by part, the only thing that makes a
difference is the diversion services.
The reason for this remains unknown for me.
I use a fritz pnp/isa card, driver compiled as a module.
No SMP, isdn in kernel.
Close to nothing running during the hangup.
The problem is reproducable and i would be glad to help testing any
suggestions.
