[asterisk-users] Possible Dahdi compile problem

[Doug]

Sorry the extra post was a mistake.

Dahdi is required by Asterisk for pseudo and timing purposes in my application even though no modules are installed. 


It is not a hardware problem but rather I suspect something in the kernel<>dahdi or kernel<>asterisk interface as they are compiled agains one another. The fact that it works for awhile then crashes is kind of strange. I was just wondering if a kernel compile mismatch would show up immediately or do something like this?

                          so this must be compiled from source. I
                          believe I have the proper header and source
                          files for the running kernel. Both dahdi and
                          asterisk compile and install. When run
                          asterisk runs for anywhere from 10 minutes to
                          a half hour or more and crashes. This is a
                          complete system crash requiring a reboot.
                          There are no indications of why it crashed. No
                          messages and analyzing memory and other
                          parameters before the crash show nothing
                          unusual.

                          the bone43 is the patched 3.8.13 kernel for
                          the Beagle Black. The patches are installed in
                          the sources but dahdi insists on putting the
                          modules in 3.8.13  and they are not found
                          there.
