<pre>We are working on a prototype Atom-based computer and dmesg shows this warning
on boot:
[drm:intel_enable_lvds] *ERROR* timed out waiting for panel to power on
The machine does have LVDS and is working great.
However, after resuming from S3 suspend, these warnings also appear in dmesg:
WARNING: at drivers/gpu/drm/i915/intel_display.c:3927
intel_modeset_check_state+0xbd/0x539()
active connector not linked to encoder
WARNING: at drivers/gpu/drm/i915/intel_display.c:3933
intel_modeset_check_state+0x119/0x539()
WARNING: at drivers/gpu/drm/i915/intel_display.c:7873
intel_modeset_check_state+0x4d3/0x539()
encoder's active_connectors set, but no crtc
WARNING: at drivers/gpu/drm/i915/intel_display.c:7892
intel_modeset_check_state+0x2c8/0x539()
encoder's computed active state doesn't match tracked active state (expected 0,
found 1)
Full dmesg is also attached. The machine otherwise works okay with modesetting.
Are the warnings unneeded or is the video chip and the LVDS wired improperly
somehow?</pre>
