I have had chrome give a GPU hang with "ring hung" after updating my system in the last few days.

For what it's worth, I am using the same version of google-chrome with the same intel graphics (rev 09 also) on Arch X64 and have never seen that, although I am using GNOME3.

OK I don't know if it is KDE specific and might also be triggered by particular web site graphics. It has happened to me about 4 times in a couple of days but when it happened then chrome is unrecoverable unless the processes are killed. At least the journal log is clear about what happened and there is a good error log generated so hopefully this will be enough to give the developers sufficient information to find where the code failed.

Thanks - those two bug reports look possibly related - I will add the links in a comment to the fly spray report and kernel bug.

For workaround use UXA over SNA

OP, note also to my comment above that I have been using glamor acceleration, not sna or uxa.

Interesting! I will have to look up how to set the system to use glamour accel and see if it makes a difference.

Changing from the default sna to uxa or glamour is trivial. See http://wiki.archlinux.org/index.php/Intel#SNA_issues. By default, sna gives me (and probably you with the same graphics) jittery window scaling animation unless I set the TearFree option. Glamor does not need TearFree.

I've been using the default sna accel for quite a while and it's generally been OK. I see that there is a new upstream version of chrome stable today so I will wait and try the new version when the aur package updates and if I still see any hangs I will switch to glamor as I have never tried it before. Having said that I have not had chrome crash since reporting the issue on my machine! I have also updated to pull in the new xorg-init a short time ago and rebooted so will test over a period and see if I get further problems - mostly it's fine though there are some issues with highlight colouring on the same machine in chrome (and Thunderbird though I am not using stock but have been in Aurora channel for quite a while).

Many of us have - but a somewhat recent update of the mesa/intel-dri drivers has killed SNA for very many intel users. I've seen countless issues solved over the past month by switching to uxa. It is a known upstream issue with the recent SNA acceleration which allegedly has a patch ready that should be incorporated soon.

Thanks you for the additional information, Trilby. Hopefully the patch you refer to will get into the released packages soon.

mcloaked, I suspect many people haven't consciously noticed the window scaling issues currently exhibited by default sna. Bring up a heap of large windows and switch in and out of the GNOME overview. Then try glamor, or uxa, (or sna + TearFree) and you may notice like on my similar system that the window scaling in and out of the overview is much smoother than default sna.

I guess that is worth trying if you are a gnome user but I only use kde so maybe the graphics issues are different.
