FATAL: Module dahdi not found

asterisknow 1.5.0 (final)
yum updated to asterisk-current

/* the system name happens to be named trixbox1 but is an asterisknow system */

Did a usual routine yum update and it succeeded. Consequently, we’re getting the following …

Noticed – during the update process – the DAHDI modules and linux kernel being “updated” included the tag (sub-class) “PAE” which I don’t recall seeing before. Not guru enough to backtrack.

We’re 100% SIP shop so running DAHDI-free does seem to have impaired anything, though I understand “t” and “paging” options (and their like) may be messed up without dahdi_dummy (or something).

Any help getting us “normal” would be greatly appreciated.



Did a free asterisknow 1.5.0 (final) install to a USB flash key and a YUM UPDATE to a fresh system.

Same errors.

There’s something amiss in the linux-kernel, asterisk, and dahdi modules. As mentioned before it may have something to do with one thinking PAE sub-class and the others not.


The YUM UPDATE, available to me on 2009/2/22 16:00 ET, comprised of

code: dahdi-linux-kmod-base-
(2/3): kmod-dahdi-linux-
(3/3): kmod-dahdi-linux-PAE-[/code]

solved the whole suite of DAHDI issues.
