 OK, thanks for clarifying.

 Are you sure that patch was the culprit?  I cannot
 reproduce the panic easily; it appeared only once
 after 5 weeks uptime on our machine.  I notice this
 machine still has rev. 1.385 (the last update was
 just one day before the commit).  So maybe it's time
 for the next update.
 
 Thanks again for the information.
 
 Best regards
