Ok, further searching showed that the commit that actually solves this problem is a merge branch 'for-linus' .
Specifically this one: [7d1419f30cc5106196e54a282d7e115e698c95f6] Merge branch 'for-linus' of git://git.samba.org/sfrench/cifs-2.6 I will say the truth that this one tricked me a lot. I didn't look at the merge itself, but from the title and the description of the commit (samba..), I considered this as the last one possible to fix my issue. BUT, because this is a merge it has a bunch of stuff (patches) there and some of them are directly related with the nouveau_fbcon and nouveau_drm. We can see the relevant patches here: https://git.samba.org/?p=sfrench/cifs-2.6.git;a=commitdiff;h=7d1419f30cc5106196e54a282d7e115e698c95f6;hp=1209bbdff2f6bbffa6eb5823033bbd7b8799a5e2 I have “cherry-picked” from the second parent, which actually holds the patches I care, and then built and tested the *real* bad kernel (3.17-rc7) and it's worked as expected. Do you want me to *try* building an Ubuntu kernel (say the affected one - 3.16.0-23-generic) with this commit(merge) and upload into a PPA, or is not necessary ? ** Attachment added: "Merge branch 'for-linus' of git.samba.org" https://bugs.launchpad.net/linux/+bug/1386695/+attachment/4249578/+files/7d1419f30cc5106196e54a282d7e115e698c95f6 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386695 Title: [3.16.0-23] Resume from suspend/hibernation, GPU lock - possible regression To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1386695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
