Fine, this already narrows down the code region in question pretty much.

Ah, LZS compression!
Does the crash also occur if you enable CCP, but disable only
lzs compression (`-lzs' option)?
Please bear in mind:
1) LZS (=Stac) compression is alpha
2) LZS is not shipped with the standard kernel due to patent problems
in certain countries.
(2) implies that you need to compile the isdn_lzscomp.c sources
from the isdn4k_utils yourself (against the proper kernel header files)
and to insmod it before the ppp session.
Have you done so?
Does `lsmod' before starting ppp indicate that isdn_lzscomp is loaded?
Is there an isdn_lzscomp.o below /lib/modules/2.4.0-test9/?
Could it be that an old version of isdn_lzscomp is loaded into the new
kernel without insmod warning about this?
Except for the last scenario, the kernel should never crash. Everything
else would be a bug in the isdn code.

I guess that's not that important right now. The last CCP konsole messages
resulting from ipppd's kdebug option are probably more informative. But
first, the answers to the questions above and a test with `-lzs' should
be even more important.
