Could you give this patch a try? https://lists.freedesktop.org/archives/intel-gfx/2016-July/099939.html I don't believe anyone outside Intel have received a KBL-H or DT with Kabypoint PCH, but it is possible, so might be worth to try the patch. The logs really looks like the logs I saw on a KBL with KBP here without this patch, so Ander might be right. Anyways, Timo, could you please provide a full dmesg with drm.debug=0xe? Also probably good if you can add a print on the intel_detect_pch function showing the pch id just in case.... I'll have a test result of the patch quicker than a debug dmesg :) Yep, the patch works, thanks. Thanks for the confirmation. Patch is now merged on dinq. Thanks for the nice post here i am follow the some easily step https://enablecookieswindows10.com/ and learn the information how to enable cookies in windows 10 edge thnaks for the visit. |
