Dmesg using Linux 4.1.10 kernel from koji
I tried with Linux 4.1.10 kernel from koji but the result stayed the same (full dmesg attached):
[ 54.292865] nouveau E[ PFIFO][0000:01:00.0] read fault at 0x0000011000 [UNSUPPORTED_KIND] from PBDMA0/HOST on channel 0x007ed7a000 [unknown]
[ 55.628377] nouveau E[ DRM] GPU lockup - switching to software fbcon
It actually looks like it must be caused by some user space changes as even the older 4.1.x kernels I have still installed back from F22 cause the same crash when now attempting to use them with F23.
Booting with nouveau.noaccel=1 (kudos to Ilia Mirkin) actually got me my desktop back but as one might imagine with my 2560x1440 screen everything is rather slow. I am really wondering what changed as F22 used to work just fine before on that exact same hardware. Unfortunately as I live upgraded to F23 I don't think there is an easy way back now.
I'm seeing this to. But not immediately at login, but sometimes when a new window is opened in gnome-shell.

journal from boot to hang
Attached the kernel logs from boot until the hang.
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bug reports from releases that are no longer maintained.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no longer maintained, which means that it will not receive any further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
Thank you for reporting this bug and we are sorry it could not be fixed.
