I hope commit 0c82312f3f15538f4e6ceda2a82caee8fbac4501 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Dec 4 16:05:26 2015 +0000 drm/i915: Pin the ifbdev for the info->system_base GGTT mmapping helps. Hmm, that patch lost the stable tags. I found your commit ID as https://patchwork.freedesktop.org/patch/67152/ Unfortunately, it does not apply cleanly to kernel 4.4 final. Can you backport it please?

Please try current Linus' master, it's there. I will test it. Will these i915 changes get into 4.4.x? Kernel 4.5.0-rc1 seems to solve this problem. The machine survives heavy switching back and forth between X and the console. I will leave it running for the night to see it survives a few hours uptime. The machine survived the night and I can still switch between X and console. When will this code go to a stable release? Can we expect it in 4.4.1? *** Bug 92119 has been marked as a duplicate of this bug. *** Is it possible for the developers to backport this and related fixes to 4.4? I've tried to do this one here on my own (without comprehensive programming knowledge), and it works somehow, but doesn't survive a resume from disk, so most likely there are other issues involved and there may be fixes for the latter, that I haven't found so far. In the current shape as of 4.4.2 i915 it's not really usable -- to tell it honestly. Best regards and thank you for your work, Manuel Krause There are still people suffering this bug downstream on gentoo even with kernel 4.4.10. It would be interesting to be able to get the patch backported to this LTS branch. I have tried to see if other distributions were able to backport it already but I didn't found it :( Thanks a lot From upstream perspective this is fixed. Closing as such. Unfortunately, the commit doesn't backport cleanly to v4.4 or earlier. Chris, if the backport is trivial, please provide a patch for it. |
