Created attachment 97653 [details] garbage.3gp Enter to init 3, the issue still existed. Remove i915, then enter to init 3, there is no garbage. Kernel 3.14 also has the issue. The issue only happens on the notebook with LCD:15", FHD, O-FLIM Please refer attachment video. Please help to check it. if you need any information, please tell me. Thanks!
Is this a regression, i.e. did it work with some kernel version? Please clarify, does the problem appear only after loading i915?
kernel 3.9 and kernel 3.14 both doesn't work. Yes, the garbage will appear after loading i915. Thanks!
Please attach dmesg with drm.debug=0xe module parameter. Let's see if there's anything out of the ordinary.
Created attachment 97895 [details] dmesg added drm.debug=0xe Please refer the dmesg.
That the HDMI1 is being probed several times per frame is definitely out-of-the-ordinary.
Whether i915 will fix the issue? Thanks!
Please try drm-intel-nightly from http://cgit.freedesktop.org/drm-intel and attach dmesg for that.
Created attachment 98218 [details] dmesg with drm-intel-nightly-0428 Update kerne t0 drm-intel-nightly 0428, garbage doesn't show. i915 has loaded but it can't enter to OS. Attachment dmesg_0430.log is the dmesg, please refer it.
