--- Comment #30 from Zoltán Böszörményi <zboszor at pr.hu> ---
The previous test was wrong, the patch to increase the panel power on timeout
from 1 second to 2 seconds was still applied accidentally.

Since the other patch to tone down the DRM messages to one liners, I get this
at boot:

[    8.897390] [drm:intel_enable_lvds [i915]] *ERROR* timed out waiting for
panel to power on

and later when resuming from S3 suspend:

So, we still need to raise the panel power on timeout.
