[asterisk-users] Possible Dahdi compile problem

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?

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

>>>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
>>>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
Alarms IRQ bpviol CRC4
>>>beaglebone*CLI> dahdi show channels
>>> Chan Extension Context Language
>>> pseudo 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.
