I'm not sure if you can easily get any debug info from this. I suspect it is
similar to the issue I am having with some ATI cards where the XServer
locks up in a tight loop within the kernel (probably DRM driver). I guess
you cannot kill the XServer either....
There is some debug ability in the drm module, not sure how to use this though.
I would suggest having a look at the freedesktop bugzilla at: 
https://bugs.freedesktop.org/. Search under the product xorg for your
graphics chipset (lspci) and/or "lockup" and filing any extra info you
have there.
I have been trying the latest git freedesktop code for ATI chipsets,
unfortunately, it does not fix the bugs I am seeing as yet.
