-----------------------------------

Hi guys, I now have the A4B controller and having some trouble getting it recognized. It appears to have loaded the right modules, but it's not recognized.

# dmesg|grep dahdi

I also tried building/installing from source and it also resulted in the same error message.

> Linux kernel 5.0 has changed the timekeeping interfaces to fix the 2038 problem.
> I believe the drivers should be standardized on ktime for internal time, but before making any changes to the app drivers, I was looking for some early feedback on the proposed approach.
> The work is currently at http://git.asterisk.org/gitweb/?p=team/sruffell/dahdi-linux.git;a=shortlog;h=refs/heads/for-5.0 if anyone has any comments.
