Hey guys, I´m updating from Zaptel to DAHDI drivers, I have an TDM400 and a TDM2400 … I´ve installed the dahdi current, with no errors on compilation, when I restarted my server, i got this error when trying to load DAHDI:

My kernel is 2.6.30.5…

Any ideas? Thanks!

maybe your kernel is too new.

3

Same problem. I ran an update yesterday and now my Asterisk in not operational. Anytime it does anything with a call it disconnects.

How do I downgrade my kernel?

4

Depends on your OS. For CentOS, assuming that the earlier kernel was ever installed, edit the grub configuration to make the earlier kernel the default.

Is .30. beta or released? There was a recent Asterisk issue that was rejected on the grounds that they would not adapt the code for a beta kernel. However, if this is a release kernel, you should raise a bug report.

I have had this system installed for over a year. All of a sudden it starts to fail. I have dahdi installed but it fails at start up.

6

You are contradicting yourself.

No. the system has been installed for over a year. I do a yum update every week. The last one seems to have made dahdi not work.
