Description hoboprimate 2016-11-03 22:24:22 UTC
Created attachment 127737 [details] dmesg I have a dual-graphics laptop, intel+nvidia. With the 'nouveau' module loaded, the laptop doesn't resume fully, with the screen staying blank. 'rmmod'-ing the nouveau driver, resuming works fine. This used to work in the past few years, the problem appeared with Fedora 25.
Comment 4 Pierre Moreau 2016-11-04 07:48:05 UTC
Support for GM108 chipsets was merged in Linux 4.7, which was released end of July 2016, so I assume that it worked before as Nouveau failed to recognise the chipset, and therefore did nothing. Trying Linux 4.7 and making sure that the chipset is recognised would be nice, to rule out a possible regression. Could you also please add the output of acpidump to the bug report?

Created attachment 127777 [details] 'journalctl -b' output when running kernel 4.7
Comment 7 hoboprimate 2016-11-04 23:49:04 UTC
Took a while to compile the 4.7 kernel :) (from fedora sources), and the chipset was recognized with it (see attached log). Resuming from suspend also failed there. Also attached acpidump output. Also just realized, I have not been attaching *full* boot logs, i.e., up to the point it fails to wake from suspension. I will do that (right after this comment) on the current 4.8.4 kernel.

Possibly a duplicate of bug 98398, can you try the ACPICA patches at https://bugs.acpica.org/show_bug.cgi?id=1333#c45

(In reply to Peter Wu from comment #9) > Possibly a duplicate of bug 98398, can you try the ACPICA patches at > https://bugs.acpica.org/show_bug.cgi?id=1333#c45 Sorry for late replying, but applying the 3 patches in compiled kernel version 4.9 fixes the problem.
Comment 11 hoboprimate 2016-12-10 23:19:00 UTC
I mean, I had to compile 4.9 with the patches, of course.
Comment 12 hoboprimate 2017-06-10 00:31:22 UTC
Using the latest Fedora 26 (alpha), suspension is working fine with nouveau loaded :) . Linux version is 4.11.3-302 . Closing this report.

Just re-opening because I'm still having some occasional failed resumes, where the display becomes visible showing gnome's lock screen, but otherwise the laptop remains unresponsive.
