I am having problems with system crashes in a dahdi/asterisk compile. The is on a Beaglebone Black running Debian 3.8.13 kernel.

Dahdi is patched and asterisk is also custom 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.

This same package arrangement works fine on several other platforms so I discount a problem in the code.

On thing that may give a clue is that when dahdi is installed it creates and puts its modules in /lib/modules/3.8.13 The system modules are in /lib/modules/3.8.13-bone43 - 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.

I have to mv /lib/modules/3.8.13/dahdi to /lib/modules/3.8.13-bone43 and then do a depmod -a 3.8.13-bone43

Then dahdi installs. I do not use any dahdi modules so no modules install.

In asterisk I get the following -

beaglebone*CLI> dahdi show status
Description Alarms IRQ bpviol CRC4

beaglebone*CLI> dahdi show channels
Chan Extension Context Language MOH Interpret
pseudo default default


If dahdi installs and at least appears to work with asterisk does that mean that it is compiled correctly? I am trying to figure out what might be causing this problem.

Possible hardware issue?
If you are not using DAHDI, why are you installing it?


Did you intend to add some information to this post that was made earlier today?

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?
