[ILUG] More ISDN distress :(

[ILUG] More ISDN distress :(

Ok so everyone is talking about their ISDN problems, I might as well
share mine ....

I used use my old P166 to connect to the net over my ISDN line (single channel
64k to oceanfree). All worked ok for a few weeks, then the connection started
becoming unstable. It frequently dropped connections (requiring either a
reload of the module or a full power cycle of the box). Occasionally the box
would hang or the screen would fill with rubbish followed by a reboot moments
later. 

I suspected anything from a faulty TA to hardware problems. I did not expect
a bad line could cause the box to crash. 

I also had a P3-700 on my home network so I added a new PCI ISDN card to this. 
This box has therefore completely different hardware, a new TA and even the
cable to the wall box has been changed.

However, I am still getting the same problem - frequent dropouts, occasional
crashes, most of the time requiring a reload or reboot to fix. 

Anyone have *any* idea what could be going wrong here ?. The connection is fine when it works, and I find it hard to believe that a signal from an ISDN line
could cause memory corruption or break a driver sufficiently to require a 
reboot. Needless to say this problem has been driving me mad!

Oh to keep it on topic, Im using Linux 2.4.18 (stock Debian kernel) with the
HiSax driver ...
