Bug 34643

Created attachment 43736 [details]
gdb/ut2k4 output and backraces.

ut2004(32/64bit) and doom3(32bit) are looping everytime in submenu on r300g/PageFlip. I believe that bug occured during last two weeks, but bisecting would be hard, because I was bisecting for:
https://bugs.freedesktop.org/show_bug.cgi?id=34418

And everytime supertuxkart wasnt working, ut2k4 also and vice versa, altough bugs were definitely different. Now previous bug is fixed(which affected only 64bit apps), but ut2004/doom3 got very similar behaviour(like looped video tape or something, moving forward and back), similar spam in console, but a bit different at output.
Disabling PageFLip fixes this problem definitely, but I was happpy pflip user from a long time.
Kernel is fresh D-R-T, DDX/DRM/Mesa from master.
