** Description changed:

  Binary package hint: xorg
  
  I'm unable to resume from S4 on a Lenovo ThinkPad SL510 w/ ATI Mobility
  Radeon 4570 (1002:9553). Upon entering S4, the graphics become corrupt -
  it looks a bit like an X11 stipple or that checkerboard that used to be
  the X background (though it's not just B&W, there is some R/G/B in the
  pattern. The pattern is not as random as static; it appears tiled, as if
  we're displaying tiles populated with corrupt video memory.
  
  On resume from hibernate, the BIOS logo is not corrupt and the (not-
  corrupted) plymouth logo flashes for an instant. There are several
  seconds of a flashing white cursor at the top left of the screen too.
  Once X comes back I see the stipple pattern/corruption again. Both the X
  and console sessions are corrupted. There is a separate corrupt tile
  surrounding the mouse cursor (the cursor itself is not visible). Moving
  the mouse cursor results in the mouse-tile moving around. The machine is
  otherwise functional - I can (blindly) login to a console on a VT and
  execute commands.
  
  Syslog from the failed resume session shows errors from drm:radeon,
  starting with:
  
  Dec 19 14:36:49 ubuntu-ThinkPad-SL510 kernel: [ 1026.671568] [drm:r600_ring_test] *ERROR* radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD)
  Dec 19 14:36:49 ubuntu-ThinkPad-SL510 kernel: [ 1026.671570] [drm:rv770_resume] *ERROR* r600 startup failed on resume
  
  If I disable the radeon driver by adding, e.g., the made-up
  'radeon.nofailboat=1' kernel parameter, the machine enters and resumes
  from S4 normally, with no corruption upon either entering or resuming
  from S4.
  
  I've reproduced in both the stock 10.10 kernel and the daily natty
  kernel (2.6.37-999-generic #201012200905).
