Created attachment 911628 [details]
journalctl -k -b -1

Description of problem:  When booting system, hard lock with nouveau errors.


Version-Release number of selected component (if applicable): kernel-3.14.8-200.fc20.x86_64


How reproducible:  Every time I boot to kernel-3.14.8-200.fc20.x86_64 I get a bunch of errors like the one listed in the summary and then the system locks up without displaying beyond the errors.   kernel: nouveau W[   PFIFO][0000:01:00.0] INTR 0x00000100: 0x00000006

Steps to Reproduce:
1.  Select kernel-3.14.8-200.fc20.x86_64 at boot


Actual results:
Unusable laptop.


Expected results:
Usable laptop.

Additional info:
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [Quadro NVS 4200M] (rev a1)

It seems like every third update to the kernel package breaks nouveau these days.  If I can help figure out what it is that is going on, let me know.  Attaching journalctl logs.

Laptop is Lenovo T420.  I disabled nVidia Optimus in BIOS and everything behaves again.

Comment 2 Fedora End Of Life 2015-05-29 12:12:11 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. 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bug reports from releases that are no longer maintained.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 '20'.

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 20 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 3 Fedora End Of Life 2015-06-29 21:17:34 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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no longer maintained, which means that it will not receive any further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
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
