Thank you for the report.  Since you have Digium cards, you should call
Digium technical support for a rapid response to this issue.

Do you have a screenshot or picture of the kernel panic?  Do you expect
that the kernel panic is as simple to reproduce as simply hanging up the
call from the FXS port?  I would have assumed we would have caught that
with automated testing.  Unless it is very easy to reproduce, we'll likely
need the config files.
