There were no specific steps that I could do to preproduce a crash other than just pressing buttons in myth and play various videos/shows. I'm guessing this type of general usage would cause all sorts of amounts memory to be allocated/freed and eventually causing enough fragmentation for kmalloc() to crap out (as described by Graeme Wilf).
I've attached the last bit of /var/log/messages that lead up to my last crash (from this morning) as requested.
