Looks like the kernel mishandled a memory allocation failure here. https://patchwork.freedesktop.org/patch/115855/ If you were using -intel, you would not have had this issue (at least from Xorg). :| Thanks for your reply.

I don't have xf86-video-intel installed. If I understand correctly, installing it would solve this issue?

If I understand correctly, > installing it would solve this issue? If I understand correctly, the root cause would be memory exhaustion, and this WARN is more or less a victim. -intel simply wouldn't trip over this WARN, but it is not clear why we are out of memory in the first place. (That is assuming that the WARN is indeed self-inflicted, it could be something else leaving stale PTE around and not the broken error handling.) I can only add that it happened while using Firefox with lots of tabs open (my laptop has 16 GB of RAM). I also seem to recall Gnome Shell automatically restarted. It never happened again. You may apply Chris' patch https://patchwork.freedesktop.org/series/13822/ Yes, thanks. I have only seen that error once (before the patch) until now... hopefully the patch is working. Been applied upstream to the mm tree, should hit 4.10. (Hopefully with a stable tag.) Dropped from -mm, reopening. http://www.spinics.net/lists/sparclinux/msg16581.html We still have the commit in topic/core-for-CI (i.e. also in drm-tip). Folks, commit referencing to this has landed. Resolved? commit e1678f8b376e945eac64015d0b716b41d4b46f37 Author: Chris Wilson <chris@chris-wilson.co.uk> AuthorDate: Sat Oct 15 09:54:01 2016 +0100 Commit: Chris Wilson <chris@chris-wilson.co.uk> CommitDate: Tue Mar 14 14:04:03 2017 +0000 looks like this issue has been solved, waited for feedback from submitter but no respond. I will close this as fixed, however if the problem appears please open a new bug including logs Please don't close this, we only have a local fixup in topic/core-for-CI. Jari/Ricardo, this means you not tuoching this bug until it's confirmed to be actually fixed in upstream, not just in drm-tip. First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not. If bug investigation still in progress, please ignore this and I apologize! If you think this is not anymore valid, please comment to the bug that can be closed. If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug. Daniel, Chris, is this fixed in upstream now? Yes the patch is still not upstreamed: commit 5499a6a112e48ed4041e97bd5919c92b4700587f Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Oct 15 09:54:01 2016 +0100 mm/vmalloc: Replace opencoded 4-level page walkers Pasting it here so next time around everyone can check themselves. Note that the blocker was that sparc64 blew up: https://marc.info/?l=linux-kernel&m=147767512629968&w=2 THe p(In reply to Daniel Vetter from comment #14) > Yes the patch is still not upstreamed: > > commit 5499a6a112e48ed4041e97bd5919c92b4700587f > Author: Chris Wilson <chris@chris-wilson.co.uk> > Date: Sat Oct 15 09:54:01 2016 +0100 > > mm/vmalloc: Replace opencoded 4-level page walkers > > Pasting it here so next time around everyone can check themselves.
