[Asterisk-Users] mISDN Problem

[Christian Gröger]

Hi,

I compiled and installed Asterisk and mISDN yesterday. It worked after 
some errors. There's one HFC-Card which should be in nt-mode, and which 
worked yeterday with my phone here, and there's another isdn-card with a 
winbond chip i think, but i don't want to use this one at the moment.

Well, this morning i started the computer for configuring Asterisk a 
bit, but mISDN had some really strange problems... here's the dmesg part 
of it:

if i want to make a restart of mISDN with it's init script it says:

ERROR: Module mISDN_core is in use by mISDN_l2,w6692pci


And here's a list of the loaded isdn-related modules:

I am running Debian Etch, thanks for any help.
