The DAHDI developers are actively working on this issue, as we've seen a
few reports of it since DAHDI 2.3.0 was released. If possible, would you
checkout dahdi-linux SVN trunk directly from
http://svn.digium.com/svn/dahdi/linux/trunk and try that? The
development trunk already has a potential fix for this issue. If you can
try it and report back here, that would be most helpful.
