With no_wb=1 the driver goes a bit further but the X server ends up in an infinite ioctl loop and the logs are:
Which ioctl does it loop on? Please provide the Xorg.0.log file as well.
From memory, the code was 0x64, which is DRM_RADEON_GEM_WAIT_IDLE.
Note that it's normal for this ioctl to be called every time before the GPU accessible pixmap memory is accessed by the CPU. Unless the ioctl always returns an error, this may not indicate a problem on its own.
It seems to be an infinite loop, always returning EINTR because of regular SIGALRM delivery.
That does sound like the GPU locks up. Do you get any messages in dmesg about lockups and attempts to reset the GPU at any time?
No.
