--- Comment #5 from Knut Andre Tidemann <knut.tidemann at gmail.com> ---
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:
