Filtered journalctl showing the NULL pointer access at the end

Description of problem:
With the latest available i686 kernel (4.10.8-200) I am getting frequent session lockups under Gnome with Wayland. The lockups do not seem to happen if I use Gnome under Xorg. When the lockup happens, the entire screen freezes and the keyboard and mouse become unresponsive, although the disk and the WiFi card keep going. I have to hard reset the netbook in order to recover.

This lockup seems to happen more when I switch between windows while trying to move the mouse, but this is not a reliable reproducer.

The kernel logs show a very clear NULL pointer access at the moment the lockup happens. Log attached.

Version-Release number of selected component (if applicable):
xorg-x11-drv-intel-2.99.917-26.20160929.fc25.i686
kernel-PAE-core-4.10.8-200.fc25.i686


How reproducible:
Frequent

Steps to Reproduce:

Actual results:
Screen lockup

Expected results:

Comment 1 Fedora End Of Life 2017-11-16 19:26:38 UTC 
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. 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bug reports from releases that are no longer maintained.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'
of '25'.

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 25 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.
Comment 2 Alex Villacís Lasso 2017-11-16 20:56:45 UTC 
Fixed under Fedora 26 in latest kernel (but see also https://bugzilla.redhat.com/show_bug.cgi?id=1438258 and https://bugzilla.redhat.com/show_bug.cgi?id=1498725).
