Xorg.0.log after reboot to show drivers versions.
This is getting frustrating to say the least. I don't seem to be getting any assistance from anyone on what to do to try and solve this. I had another freeze this afternoon 08/24/2015 after being up for 5d 12h 3m. The system froze while I was using Firefox this time in Twitter. The freeze happened at 17:45:23. I've noted this time since I've attached the syslog up until my reboot this evening. I SSH'd into the desktop via my tablet. I ran cat /sys/class/drm/card0/error and it returned 'No error state collected'. I then ran cat /sys/kernel/debug/dri/0/i915_swizzle_info and it returned: bit6 swizzle for X-tiling = none bit6 swizzle for Y-tiling = none DDC = 0x00200010 DDC2 = 0x00300030 C0DRB3 = 0x0030 C1DRB3 = 0x0010 I've attached the kern.log and syslog. Again I'd really appreciate some kind of help on solving this issue whether it's going to a newer kernel than 4.0.0-997-generic #201503310205 SMP Tue Mar 31 02:07:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Created attachment 117900 [details]

Maybe this is related: https://bugs.freedesktop.org/show_bug.cgi?id=90155 Video froze on 1 June, no errors in syslog, such as 'hangcheck...', that I could see. Mouse cursor would move normally however no applications could be opened. Clock is frozen at the time of the freeze. Applications such as Fetchmail, Procmail and Postfix continue to run as normal. I'm currently running kernel 4.6.0-997-generic #201605222202 SMP Mon May 23 02:03:57 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux which I installed prior to this freeze. I'm attaching two files. 1. The dmesg output after the freeze, before the reboot. 2. Entries in my syslog possibly dealing with this, I don't know for sure. The file name is SRWatermark.txt This line was added to my /etc/default/grub on 23 May - GRUB_CMDLINE_LINUX_DEFAULT="drm.debug=14 plymouth:debug" Created attachment 124302 [details]

Hello Chris, Sorry for all the time this have been unattended, is really hard to work on this kind of bugs without error states logs. I can see that the latest kernel reported was 4.6 and lots of changes have been made since then. Is this problem still reproducible with the latest kernel versions? https://www.kernel.org/ Thank you. Hi Elizabeth, no, I haven't seen this issue in ages. I should have probably have added a comment to this bug to that effect but I totally forgot. Currently I'm running - 4.4.0-87-generic #110-Ubuntu SMP. I'd consider it closed if you wish. (In reply to Chris from comment #13) > Hi Elizabeth, no, I haven't seen this issue in ages.

Thank you for the feedback Chris. Then I'll proceed to close this bug. Good day :) |

Created attachment 117428 [details] Xorg GDB backtrace output Video will freeze for no specific reason and an no particular time interval. Although it does seem to happen most often when using Facebook or Twitter with Firefox the freeze today was when I was going to print a webpage from within Firefox. When the freeze happens all other background processes such as Fetchmail, Procmail, Postfix and others operate as normal. The freeze today took place at 15:36:03 CDT and I've noticed in my Syslog that at 16:02:28 there was this entry: Jul 28 16:02:28 localhost kernel: [793861.820048] [drm:i915_hangcheck_elapsed [i915]] *ERROR* Hangcheck timer elapsed... render ring idle I was able to SSH into the desktop via my tablet and did a reboot from there at 16:10. Running 'cat /sys/class/drm/card0/error showed an output of "no error state collected". System Info: Ubuntu 14.04.2 LTS Dell Optiplex 780 Kernel 4.0.0-997-generic I'm also attaching the GDB output of 'backtrace full' for Xorg and Gnome-Shell
