[Bug 588940] [NEW] Xorg freeze drm radeon 'Faild to schedule IB'

 

Public bug reported:

Binary package hint: xorg

Freezes at various times could be any time during boot or later. At
times I am able to switch to VT 1 and see error messages displayed.....

 Jun  2 12:03:49 ubuntu kernel: [  578.361780] [drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(9).
Jun  2 12:03:49 ubuntu kernel: [  578.361789] [drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !

Some times followed by a message about attempting to reset the video
card at which point system seems to be hard locked, not lights on the
keyboard, hitting the 'num lock' key doesn't cause a light to light up
and 'Sys Rq'+'B' has no effect either.
