we experience kernel panics when using our application. They are rather
mysterious and give nearly no information. Please see below. The PC and
backtrace addresses vary but a valid backtrace is never given.

It looks really ugly from here. Do you have third-party
software/hardware in your system? Additional memory? When did this
start happening (in relation to Significant Events in your system(s))?
