no, it still kills the interup-handler!!!

In my testprocedure, I only used "isdnctrl dial" followed by a sync
command, and "less /var/log/messages" and F, to see some debug-messages,
that are near the bad operation.

I think, this is the reason, logged from the remote (the non-crashing
server). The whole negotiation is done, besides CCP - IP is up. As I
fetched this file, I used on both sides Linux-2.2 with CCP/LZS
compression, as the logs stated.

When I got a little time to spare, I will dig further!

P.S.: If somebody needs the whole parts of the messages file (2 tryes, 1.
the crashed one part, and 2. the working Linux-2.2 vs Linux-2.2)
