I am just closing out this thread after Matt made his system
available for trouble shooting.

The crash reported here is fixed in 2.9.2-rc2 in commit (a1ff3cb0
"dahdi: Stop tones on channel when updating tone zone.") [1]

[1] http://git.asterisk.org/gitweb/?p=dahdi/linux.git;a=commit;h=a1ff3cb0c0f3f4e65d734f4a71a090f5484505b4

The bug in dahdi was hit in this case since dahdi_cfg was called
while asterisk had channels opened that were in the process of
playing tones.
