Description of problem:
After kernel upgrade from 4.2.8 to 4.3.5 and reboot, login to GNOME and kernel error message.
GNOME shell responds very slowly most of the times.
Multiple intel video driver backtraces are shown in dmesg. Video chipset is i945 GM.
Note that this CPU does not support PAT, and kernel 4.2 to 4.3 phased out MTRR in favor of PAT.
The same behavior was observed with kernel 4.3.3
Tried with kernel 4.4.1-300.vanilla.knurd.1.fc23.i686+PAE, seems better responding, but still multiple backtraces are shown in dmesg.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
boot the system with kernel > 4.2.8
Multiple ABRT problems and dmesg backtraces are systematically reported with 4.3.3, 4.3.5, 4.4.1
GNOME desktop responds regularly.
No backtraces, no problems in ABRT
This bug was reported via ABRT as well, and detected as duplicate of 1298878, but I see comments about wireless card there, so I submitted a new one.

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
