Kernel BUG at arch/x86_64/mm/pageattr.c:154

[Kasper Sandberg]

hello... i know my kernel is tainted, however, since the thing with
nvidia giving warnings i think this still might be apropriate to report.

i get the following by running bzflag 2.0.4 (2.0.2 works)..
the first time i did it, X froze, the next time, it didnt, however no
opengl worked anymore...
bzflag seems to be the only thing whihc doesent work, other opengl stuff
seems not to be affected, despite the warning from nvidia..

... and the nvidia module is all over the backtrace. I think this is a
clear one for reporting to nvidia instead....

okay, i just thought it was relevant to post here, since the warnings
came after the changes which made nvidia complain.. and since linus was
interrested in that i figured i might aswell post this
