Created attachment 917637 [details] Kernel trace I have managed to capture Description of problem: Since 3.15.3 (same on 3.15.4), nouveau driver fails to resume from suspend on a NV84 Core (as found on Macbook Pro 2008). Version-Release number of selected component (if applicable): 3.15.3 and 3.15.4 How reproducible: Always Steps to Reproduce: 1. Boot and log into Gnome Shell 2. Flip the LID to suspent 3. Open the LID Actual results: Garbled screen, caps lock key not responding, VT switching not working. Expected results: Back to shell unlock screen. Additional info: This is a regression from 3.14.9. I'm not sure the attach trace is what is needed to debug this issue. Instructions to betters traces are welcome.

Same problem here, with 3.15.5 kernel, MacBook Pro A1260 with fresh and only Fedora 20 EFI installation. 3.14- kernels worked fine, with rare occurrences of the garbled screen reported above. Hibernate, however, still works fine. Attached dmesg dump as suggested in http://fedoraproject.org/wiki/Common_kernel_problems#Suspend.2FResume_failure
Created attachment 919474 [details] /var/log/messages when suspending to RAM (sleep) Same problem still with 3.15.6-200.fc20.x86_64, I attach /var/log/messages when suspending to RAM and when waking (below).
Created attachment 919475 [details] /var/log/messages when waking from sleep, unsuccessfully I attach /var/log/messages when waking from sleep, before a forced reboot. This part of log is not registered in the journal.
Any info here ? passed 3.16.2, things got really worst, and Xorg don't start anymore.
Created attachment 955898 [details] journalctl -b dump with unsuccessful boot Indeed, with 3.16.6 and 3.16.7 the system fails to boot into a graphical mode altogether. I attach journactl -f dump with such a boot.
Created attachment 955901 [details] Xorg.0.log showing unsuccessful boot into graphical mode (3.16.6 and 3.16.7 kernel versions) Also attached is Xorg.0.log when running startx upon logging with CTRL+F2. For now, I put the no-delete flag to 3.16.4 kernel version and I stick to that. This is getting really serious.
I've created a seperated bug for the "no graphical boot" as per a discussion on #nouveau, these are two bugs, See bug #1161887. The report include a hacky workaround.
Return from suspend works again now on F22 (kernel 4.0.1+). I mostly tested on gnome-wayland to be honnest, but it worked when I took the time to force X to start. bug #1161887 is still there.
