Output of dmidecode

dmesg output drm.debug=0x06
We need the logs from after the "lock up". The dmesg log is after the lockup this morning, do you want me to run lshw and dmidecode and attach or do you want the actual syslog entries? This happened during the night sometime so I don't know exactly when but I did do the reboot at a bit after 7am this morning. The dmesg looks like it was captured after the reboot and not the lockup. Understand, next time there is a lockup I'll attempt to log-in and save the current dmesg file to another name before I reboot. I'd like to update a bit about this. The frequency of the 'freezes' has changed and is something lie 5 or so days now between them. Currently it has been 8 days, 20hrs since the last freeze. There is no longer the 'black screen with movable cursor' I think that may have come from when I was using X-Screensaver and it would freeze when switching between screensavers being used. What will happen now is I will be Firefox scrolling through my Facebook news feed or scrolling through tweets on Twitter I will notice the freeze. I'm able to SSH into my computer from my Amazon Fire Tablet and have done so each time doing backtraces on both Gnome-Shell and on Firefox. I have forwarded all the output files to Chris Wilson. If they need to be posted here I can do that. I am currently running kernel 4.0.0-997-generic #201503310205 SMP Tue Mar 31 02:07:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux and Module intel: vendor="X.Org Foundation"[ 49.404] compiled for 1.15.1, module version = 2.99.917 Please attach the relevant logs here too if this is still an issue. This is still an issue. The last freeze was on 12 Aug, 2015. I did not have time to do a gdb backtrace of Xorg or Gnome-Shell however running cat /sys/class/drm/card0/error it showed 'no error state collected' and cat /sys/kernel/debug/dri/0/i915_swizzle_info and got bit6 swizzle for X-tiling = none bit6 swizzle for Y-tiling = none DDC = 0x00200010 DDC2 = 0x00300030 C0DRB3 = 0x0030 C1DRB3 = 0x0010 I don't know if this is any help or not. I'm attaching the gdb backtrace outputs of kern.log, Xorg and Gnome-Shell on the previous freeze that happened on 28 July 2015. This is really getting frustrating as I don't seem to be getting any feedback lately from anyone with advice on what to try next or even saying there is nothing that can be done.

Current Xorg.0.log
(In reply to Chris from comment #13) > Created attachment 117763 [details] > Current Xorg.0.log Chris is this issue still occurring with latest component version? Not in a very long time. I'm embarrassed, I'd forgotten about this bug I'd submitted and should have posted a comment when the problem stopped so it could be closed out.
