Hi Hugh,

Just wanted to let you know that XBMC dev fritsch stated the following
regarding the use of the above kernel parameters. "We made longtime tests and
the same happens after 12 hours or more. So it seems to make the bug "more
unlikely", but if you add additional load on the GPU (as we do with v14 and the
VPP Deinterlacers), you will get the hang again."
