[Intel-gfx] [965GM kms] Many kernel warnings, resume-from-suspend broken

[Gilles-Philippe Morin]

Hello,

I am in deep trouble now that I have upgraded to Fedora 21. My main
production computer — a Dell Inspiron 1525 laptop — fails most of the time
to resume from RAM suspend and thus I cannot use it at school anymore.

At the same time, this issue is accompanied by many graphical issues. I do
not know if they are linked together.

When I say "suspend from RAM", I mean closing the lid of my laptop.
When I say "resume from suspend", I mean opening that lid.
When I say "fail to resume", I mean getting a black screen with a working
cursor and responsive keyboard. The only buttons that don't work are the
brightness buttons and the Prnt Scrn buttons. Switching to another TTY
works.

I made many dmesg outputs, after boot, after a succeeding resume, after a
failed resume in another TTY. The latter does not provide me anything
meaningful, but the two first ones are filled with warnings.

I always get a warning for the i915 GPU DRM:
https://bugzilla.redhat.com/show_bug.cgi?id=962386

At boot, my kernel gets tainted because of a graphical warning:
https://bugzilla.redhat.com/show_bug.cgi?id=1177477

After a succeeding resume, I get a firmware bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1180939

And finally, the very inconvenient resume fails:
https://bugzilla.redhat.com/show_bug.cgi?id=1176645

I also get graphical glitches from time to time, but I have no idea if they
are related to the above bugs:
https://bugzilla.redhat.com/show_bug.cgi?id=1178543

Here's my setup:
Fedora 21 Workstation
Processor: Intel® Pentium(R) Dual CPU T2390 @ 1.86GHz × 2
OS Type: 64-bit
Graphics: Intel® 965GM
GNOME: Version 3.14.2

kernel: 3.17.8-300.fc21.x86_64
driver: xorg-x11-drv-intel-2.99.916-3.20141117.fc21.x86_64

I am willing to give any additional information that can accelerate the
solution-finding and I would need help with locating where to file the most
complete bug report possible.

Thank you.
