ISDN Router Oopses

[Klaus Pieper]

Hello,

I  use an older pc as ISDN router (Debian potato, kernel 2.2.17pre stock
from the distro, isdnutils 3.0-20, ssh-nonfree 1.2.27-6.1, wwwoffle).
The thing has never worked properly. I suspected hardware problems and
swapped the ram modules, but still have oopses.

I checked the memory with memtest86, was Ok. Had a kernel compilation
loop for one hour, also ok.

How can I make shure if the hardware is Ok?
What could be wrong with the software?

Here are some recent examples of the crashes.

TIA
Klaus
