Looks like on resume you're getting a ton of [ 75.967312] nouveau E[ PBUS][0000:01:00.0] MMIO read of 0x00000000 FAULT at 0x610260 [ IBUS ] [ 75.967343] nouveau E[ PBUS][0000:01:00.0] MMIO read of 0x00000000 FAULT at 0x610260 [ IBUS ] followed by [ 75.967345] nouveau E[ PDISP][0000:01:00.0][0xc000857b][ffff8803f3954100] timeout1: 0x00000000 [ 75.967346] nouveau E[ PDISP][0000:01:00.0][0xc000857b][ffff8803f3954100] 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" Are there any new patches to test or any hints to solve this problem? In the final kernel 3.19 the problem persists. Shall I provide further debugging information? Same problem in 4.0rc2 Is "suspend to disk"-support planned for driver nouveau? (In reply to B. A. from comment #10) > Is "suspend to disk"-support planned for driver nouveau? 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.

Created attachment 113124 [details] 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; [ 101.332] nouveau_exa_upload_to_screen:380 - falling back to memcpy ignores tiling [ 101.348] nouveau_exa_download_from_screen:295 - falling back to memcpy ignores tiling [ 101.348] (EE) [ 101.348] (EE) Backtrace: [ 101.348] (EE) 0: /usr/bin/X (xorg_backtrace+0x48) [0x7fbef984ae18] [ 101.349] (EE) 1: /usr/bin/X (0x7fbef96a6000+0x1a8e59) [0x7fbef984ee59] [ 101.349] (EE) 2: /lib/x86_64-linux-gnu/libc.so.6 (0x7fbef7826000+0x36d40) [0x7fbef785cd40] [ 101.349] (EE) 3: /lib/x86_64-linux-gnu/libc.so.6 (0x7fbef7826000+0x98d66) [0x7fbef78bed66] [ 101.349] (EE) 4: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x5356) [0x7fbef3352356] [ 101.349] (EE) 5: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x57fb) [0x7fbef33527fb] [ 101.349] (EE) 6: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x7e22) [0x7fbef3354e22] [ 101.349] (EE) 7: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x100c2) [0x7fbef335d0c2] [ 101.349] (EE) 8: /usr/lib/xorg/modules/libexa.so (0x7fbef334d000+0x8499) [0x7fbef3355499] [ 101.349] (EE) 9: /usr/bin/X (0x7fbef96a6000+0x131af9) [0x7fbef97d7af9] [ 101.349] (EE) 10: /usr/bin/X (0x7fbef96a6000+0x50281) [0x7fbef96f6281] [ 101.349] (EE) 11: /usr/bin/X (0x7fbef96a6000+0x5339e) [0x7fbef96f939e] [ 101.349] (EE) 12: /usr/bin/X (0x7fbef96a6000+0x571ea) [0x7fbef96fd1ea] [ 101.349] (EE) 13: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xf5) [0x7fbef7847ec5] [ 101.349] (EE) 14: /usr/bin/X (0x7fbef96a6000+0x4276e) [0x7fbef96e876e] [ 101.349] (EE) [ 101.349] (EE) Segmentation fault at address 0x0 [ 101.349] (EE) Fatal server error: [ 101.349] (EE) Caught signal 11 (Segmentation fault).
