Also getting the same problem using fritch's build here
https://github.com/fritsch/linux that has that patch, on ubuntu saucy with xbmc
using vdpau. Card in this instance is a radeon HD 7750.

The surviving dmesg.0 and syslog from that session doesn't show any information
related to the crash. If anything it crashed the system more thoroughly and
quickly than the mainline kernels, requiring a reset-button press to recover.
