--- Comment #14 from Pavel Petrovic <ppetrovic at acm.org> ---
I think it is not fixed. At least not the timeout part.
As suggested in comment #7 by Ville Syrjala, one second (as appears even in the
latest official kernel source code) is not sufficient.

I have a TOSHIBA Protege laptop with Lubuntu, freshly upgraded to 18.04 beta,
with:

00:00.0 Host bridge: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and
945GT Express Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML
Express Integrated Graphics Controller (rev 03)

and the logs during power on boot (not resume or anything similar, just plain
power on) contain the following message:

[   25.044184] [drm:intel_enable_lvds [i915]] *ERROR* timed out waiting for
panel to power on

I am attaching dmesg_toshiba_portege.txt with 

drm.debug=0xe log_bug_len=2M 

grub option.
