--- Comment #15 from Chris Wilson <chris at chris-wilson.co.uk> ---
Have you checked for a bios update? The essence of the problem is that the bios
provides a value that seems to cause a lockup. To prevent us using that value,
we can do "cat /sys/class/drm/card0/gt_max_freq_mhz >
/sys/class/drm/card0/gt_boost_freq_mhz".
