syslog messages standy and resume - working

Hello,

I use Kubuntu 14.04.x together with a nvidia graphics card NVC1 (GF108) GT 430
passive and driver nouveau. 

Standby and resume works with the nouveau driver, but hibernate and resume
don't.

There is a black screen after resume, then the monitor goes off (no signal) and
no keyboard input is possible => Only a hard reset helps.

*** Package versions
Kubuntu 14.04.1 64bit
nouveau version 1.0.11-1-ubuntu2~trusty
Mesa 10.3.2, Xserver 1.16.0 (Utopic (14.10) Xstack)
kernel 3.16.x (also tested kernel 3.18.5 and 3.19rc7)

I have attached the following logs; with kernel parameter nouveau.debug=trace

--- syslog and xorg.log for the working standby 
syslog_standby_resume.txt    
standby_resume_Xorg.0.log.old_working.txt

--- syslog and xorg.log for the (hibernate) and resume problem 
syslog_hibernate_resume_NOT_working.txt
hibernate_resume_Xorg.0.log.old_NOT_working.txt

--- lspci.txt

There is a crash at the xserver;

Looks like on resume you're getting a ton of

followed by

init failed, -16

and some other init failures. When the card fails to come up, X isn't
particularly happy about that either, hence the black screen and general state
of sadness. So the question is why does the card not come up properly...

By the way, when you say "standby" I assume you mean "suspend to ram", while
when you say "hibernate", I assume you mean "suspend to disk" right?

Yes, you are correct;

"standby" = "suspend to ram"
"hibernate" = "suspend to disk"

In the final kernel 3.19 the problem persists. 

Shall I provide further debugging information?

It's not broken on purpose... I believe it *ought* to work. It'll just require
someone to debug this to figure out what's going wrong.

What can I do to help you to debug this problem? 

NVC3 also seems to have this problem:
=> see bug
https://bugs.freedesktop.org/show_bug.cgi?id=67255

Is the NVC0 family (Fermi) in general broken with hibernate and resume, or is
it dependent on the model of the graphics card?

No clue. It could also be a new issue introduced with a recent kernel change
(like all the fencing changes that have gone in). Or it could be an issue as
old as time itself :)

If this were easy to figure out, someone would have already done it. I haven't
a clue how to debug this... resume issues are notoriously difficult to
investigate.

Thank you for the answer!

I test this issue since kernel 3.2 and with other kernel versions (LTS kernel
version from Ubuntu LTS point releases), but it never had worked.

B. A., given you are using a downstream version of nouveau, it will help
immensely if you filed a new report with Ubuntu by ensuring you have the
package xdiagnose installed, and that you click the Yes button for attaching
additional debugging information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.

For more on why this is helpful, please see
