[Felix Geyer]

This commit made it into Mesa 7.10.2 so upgrading to the new upstream
release would be another option.

Title:
  R600 driver crashes when adding effects in kwin

Status in “mesa” package in Ubuntu:
  Triaged

Bug description:
  Seen on a radeon mobility 5650.
  When changing settings for kwin (the KDE window manager) it sometimes crashes with the top of the stack trace in r600_dri.so 
  top of stack was at r600_bo -> r600_buffer_create
  Saw a suggestion in debian bug 612609 to try to cherry pick 63b9790a55038c262b57c846a5f7067ea33fc60f from mesa master.
  Haven't seen the crash since.
