uname: Linux terra 4.6.0-1-amd64 #1 SMP Debian 4.6.4-1 (2016-07-18) x86_64 GNU/Linux This reads like a desync of some sort. The most common cause of this is the fact that nouveau + threading = fail. I have some preliminary patches which kinda-sorta work but not quite done that you can try - https://github.com/imirkin/mesa/commits/locking Chances are you can ssh in from another computer and kill the offending process and then things should come back. Not always though. WOW. You do quite a work there, aren't you. Thanks, I will try and build it soon from source but as this is my work machine, it is not quite sure that this will be tomorrow. (In reply to wadev from comment #3) > WOW.

Until then, you can disable all the webgl/acceleration stuff in firefox and it should hopefully not happen again. I believe this can be done from about:config. Um, wait, what? now this was a straightforward build process. I managed to build it in the background in say, 7 minutes. I have to leave the office now and have to leave something running, but will test it tomorrow and get back to you. Thanks for assistance. PS. I had no luck with the usual config settings (not that two changes per hang is viable even on the medium run). Sorry that I did not manage a proper install till today. Seems that things changed somewhat. Symptom is the same, but the message is now different. Now I have this: Aug 31 16:41:52 terra kernel: nouveau 0000:01:00.0: gr: DATA_ERROR 0000000c [INVALID_BITFIELD] ch 7 [007f9ed000 Compositor[5572]] subc 0 class 9297 mthd 0808 data 80000585 Aug 31

Now it became more interesting. I "downgraded" to Jessie (clean install), 3.16.0-4, with OpenGL vendor string: nouveau OpenGL renderer string: Gallium 0.4 on NVD9 OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile ..and I still have the problem :/ The log messages are, however, different. I add some here should it help anybody somewhat.

I opened a bug report against Firefox https://bugzilla.mozilla.org/show_bug.cgi?id=1302974 As you can see there it seem that is "user_pref("layers.acceleration.force-enabled", true);" that make Firefox crash. If I set it to false Google Maps works. To confirm with a clean profile, Firefox crash on Google Maps with just this setting enabled "user_pref("layers.acceleration.force-enabled", true);". Weirdly it make Firefox crash only on Google Maps. Unfortunately I, and a lot of people I guess, need this feature to get rid of tearing. Firefox doesn't crash in safe mode.

No dice, I am still having the problem. In the meantime, today I tried it with OpenGL vendor string: nouveau OpenGL renderer string: Gallium 0.4 on NVD9 OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.2 OpenGL core profile shading language version string: 3.30 on Debian Jessie. it does exactly the same (with hardware acceleration enabled).

I'm having similar problems (google maps in firefox reliably causes a freeze, although my mouse and magic-sysrq work); in my case, the logging grinds to a halt with a fifo engine fault it doesn't seem to recover from. I've also found that spherical video on youtube does it reliably, other video does it occasionally, and other firefox usage does it rarely. This is my home computer, so I can mess around with it some more if you want extra debugging output or something. (In reply to wadev from comment #13) > Paviluf, could you please mention your firefox version and the output of > your glxinfo - at least the core profile one pertaining to mesa version? I can't since I'm on Nvidia proprietary drivers for now. If I switch back to nouveau I will do it, if I remember :D I recently tried Fedora 25 and it seem to work with nouveau dri2 and dri3 now. By the way, are we reporting this at the right place ? There is also Mesa/DRI/Nouveau that seem more appropriate to me. Wow, thanks, I couldn't have guessed that. :D Changed now. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

When visiting Google Maps website from Firefox 49.0b5, the computer totally locks up. It becomes unresponsive, no keyboard input (not even leds) nor mouse activity from there on.
