[Bug 561554] Re: [KMS] Desktop freeze + radeon IB schedule errors

[Ancoron Luziferis]

Just some very similar thing occurred with a completely different setup:

- ATI Radeon HD4770
- Dell 3007WFP-HC (2560x1600)

The first error message is the same:

[  859.792340] [drm:radeon_fence_wait] *ERROR*
fence(ffff880086501240:0x00042766) 510ms timeout going to reset GPU


So I think this is the same issue, although the resulting output differs a lot (could just be different code paths between r500 and r700 GPU driver/drm code).

Attached is the kern.log of the complete session.

The driver itself drops at some point:

[mi] EQ overflowing. The server is probably stuck in an infinite loop.
