I don't have a camera handy, but it's a grey pattern that looks a bit like an old- fashioned X11 stipple (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 Then hundreds of the following, with different values of IB Dec 19 14:36:49 ubuntu-ThinkPad-SL510 kernel: [ 1029.211800] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(11).

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.
