I've attached them to my two bug reports noted in my earlier post but I don't know if they actually show anything or not. Each time there is a freeze I run, per Chris Wilson of this list, cat /sys/class/drm/card0/error which always reports 'no error state collected'. I also run cat /sys/kernel/debug/dri/0/i915_swizzle_info again as requested by Chris Wilson. The results are always the same bit6 swizzle for X-tiling = none bit6 swizzle for Y-tiling = none DDC = 0x00200010 DDC2 = 0x00300030 C0DRB3 = 0x0030 C1DRB3 = 0x0010 And not knowing what I'm looking for I don't know if the above is ok or not. I get into a real quandary when the guru's here in this list ask me to try something such as running kernel 4.0.0-997-generic #201503310205 SMP Tue Mar31 02:07:04 UTC 2015 from here http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ then when I go to report it at Ubuntu I'm told don't run this kernel it's unsupported run this one 3.19.0-30-generic #33~14.04.1-Ubuntu SMP. After noting a freeze after 1 1/2 days I was told by the Ubuntu Guru to start with the newest upstream kernel from here http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D and to attempt install until I got one to work which in this case was kernel 4.2.3-040203-generic #201510030832 SMP Sat Oct 3 12:34:31 UTC 2015. This 'video freeze' issue actually started back on 09/13/2014 when at that time my syslog would show kernel: [173977.808008] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle. At that time I was running kernel Ubuntu 3.13.0-36.63-generic 3.13.11.6. This continued on through Ubuntu kernel versions 3.13.0-37.64-generic 3.13.11.7, 3.13.0-39.66-generic 3.13.11.8, 3.13.0-40.69-generic 3.13.11.10, 3.14.0-031400-generic, 3.13.0-44.73-generic 3.13.11-ckt12, 3.13.0-45.74-generic 3.13.11-ckt13, 3.19.0-031900-generic (kernel@tangerine) During this freeze I noticed the following in my syslog - this was all prior to my reboot right after the freeze - http://pastebin.com/MpfiGqLe Continuing with kernel versions affected- 3.13.0-46.76-generic 3.13.11-ckt15, 4.0.0-040000rc2-generic - when running this kernel another trace was generated http://pastebin.com/VghUmcjx booted into kernel 4.0.0-040000rc4-generic call trace generated here also - http://pastebin.com/RdbWfFYb booted into kernel 4.0.0-997-generic from here http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ which at the time was the most current. I'd be happy to provide any other information that I can. The 'hangcheck....'error is no longer seen even though the freeze symptoms remain the same.
