ISDN/Capi Driver or PPP problem
From: Simon Natterer
Date: Wed May 05 2004 - 17:06:39 EST
Hello,
I've got a problem with Kernel 2.6.6-rc2 and my AVM-B1 PCI card
together with a PPP connection.
When using Asterisk PBX I've got strange problems like dropped
connections (ppp) or hangups.
I captured this oops:
Can anyone help me interpreting the attached file, I'm not sure
if this problem is really ISDN related or has to do with PPP.
Thanks in advance
Simon
P. S.
Do I have to run ksymoops over this data? It seems I don't get
more data with this run.
