I'm running openafs 1.4.14.1 on a RHEL6 system and under heavy load when
accessing files in AFS via apache I'm able to consistently trigger a
kernel panic. Below is the output from the "crash" command and includes
a stack back-trace.
Please let me know if/what I can do to help further troubleshoot this.

This looks similar to the panic fixed by Andrew's recent fix,
http://gerrit.openafs.org/5086
which fixes a reference count imbalance.
