from Knut Andre Tidemann
I can also reproduce this with the effects demo on this card: [AMD/ATI] Redwood XT [Radeon HD 5670/5690/5730] I was able to ssh into the machine and kill the application, which restored the display on the X server. The following output was seen repeating in the terminal output of the application: EE r600_shader.c:157 r600_pipe_shader_create - translation from TGSI failed ! EE r600_state_common.c:751 r600_shader_select - Failed to build shader variant (type=1) -1 as well as GPU lockups in the kernel like this: [3114375.931718] radeon 0000:01:00.0: ring 0 stalled for more than 10086msec [3114375.931722] radeon 0000:01:00.0: ring 0 stalled for more than 10086msec [3114375.931728] radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000004e7c894 last fence id 0x0000000004e7c891 on ring 0) [3114375.931735] radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000004e7c894 last fence id 0x0000000004e7c891 on ring 0) [3114375.931816] radeon 0000:01:00.0: failed to get a new IB (-35) [3114375.931822] [drm:radeon_cs_ib_fill] *ERROR* Failed to get ib !
