Dahdi stopped working after one week

My freepbx setup with asterisk, dahdi_tools 2.6.1 and dahdi kernel drivers from gitorious.org/dahdi-extra (the only one I found with zaphfc drivers)

Last week I installed the dahdi drivers and all went well. Today, I’m unable to recieve/make calls.
Asterisk log of incoming call : http://pastebin.com/mK9p3UvL

dahdi-channels.conf: http://pastebin.com/4SYg7Ngb

dmesg containing dahdi unload and load: http://pastebin.com/EvPd5zJB

I think that there is something wrong with the drivers. Cards are as good as new. They are from a couple of years back, but never used. I’ve got a whole stack of those lying here. btw: cards are with a cologne chipset.

Can anybody point out where the problem could be? The old configuration on asterisk with chan_misdn gives no problems whatsoever. Busting my head here…
