Created attachment 392712 [details] nouveau lockup log All the messages from the nouveau driver since system bootup.
I searched for the regression between v3.12 and v3.17. Everything up to and including v3.14 (i.e. 3.1[234]) works fine. Everything above and including v3.15 breaks. I chose to bisect changes made to drivers/gpu/drm/nouveau between these two versions. $ git --oneline --decorate --graph ^4dedde7 ^v3.14 v3.15 6ba6b7c -- drivers/gpu/drm/nouveau/ * 763b257 Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes |\ [...] * | 085969e drm/nv50/bar: fix plymouth issues on certain efi macbooks * | ecf24de (refs/bisect/bad) drm/nouveau: fix fbcon not being accelerated after suspend <-- THE BAD! * | 88e98d4 (HEAD, refs/bisect/good-88e98d49a1b3e0f8103cdd4fd80d576ec33133ab) drm/gf100-/gr: split ppc state into its subunits * | 7e19453 drm/gf100-/gf: split tpc state into its subunits [...] * | 0ac4e3a drm/nouveau/hwmon: replace strict_strtol() with kstrtol() * | aa34efe drm/nouveau/hwmon: remove some redundant checks * | 4ac1b1a drm/nv50/graph: update status enum names |/ * 44d847b drm: init TTM dev_mapping in ttm_bo_device_init() * 6796cb1 drm: use anon-inode instead of relying on cdevs * 6ba6b7c (refs/bisect/good-6ba6b7cdaf1a48b24c23c303871ffe1640a866e8) Merge tag 'drm/dp-aux-for-3.15-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next As much as such a quick bisect as mine between two different kernel patchlevels should not be trusted too much, I can say 88e98d4 works pretty nice (three resumes in a rwo without any problems) ecf24de breaks miserably. Its commit message mentions problems with switching to "software fbcon" after resume which is mentioned in my dmesg dump too. However, it appears the commit instead of fixing a problem introduced it on my hardware. It appears there has been some work done git log -U50 -p ecf24de^..torvalds/master -- drivers/gpu/drm/nouveau/nouveau_fbcon.c I will try some recent 3.19-rcX kernels and will report back.
Linus Torvalds'[1] 3.19.0-rc2-00215-gd753856 still has got the same problem. [1] git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
Booting with nouveau.nofbaccel=1 in the kernel command line as proposed[1] by Ilia Mirkin, prevents lock-ups on both 3.17.7 as well as on 3.19.0-rc2-00215-gd753856. [1] http://lists.freedesktop.org/archives/nouveau/2015-January/019633.html
Good news, closing as workaround found.
I am glad I could help. Do you think there is a place where some reference to this bug could be put to help others. How about a message in the ebild that is displayed if the nouveau driver is built?
