Comment 74 for bug 411294

I'm seeing the same issue on my T60 with the X1400 as in comment #5. Everything works until I suspend/resume, after which the whole screen is garbled and blinking, but otherwise responsive. This is with 2.6.32-rc5-git4. Unfortunately the drm-next branch didn't work (unclear why, produced a hard lockup), so I stuck with drm-linus which seemed to contain a few safe bugfixes.

After applying your proposed workaround patch, things are still not working, and the error message you added is triggered: "[drm] (rv370_pcie_gart_set_page 78) VRAM seems to not work properly !", which seems to get emitted every time I am switching between a VT and the X server (none of which puts the graphics card into a sane state), with tons of the "couldn't schedule IB(15)" around them.
