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).

Description:
Graphics get corrupted before the machine enters S4. 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.
