Correct the bug failure symptom: Test with latest drm-intel-nightly branch: Put system into S3, resume back by clicking power button,edp display show black screen after S3 resume. This was resolved on eywa kernel tree ,but still exist on the drm-intel-nightly branch kernel. Hi Xu Bin, please add "log_buf_len=4M" to kernel parameter to get the full dmesg log. Damien, are these [1] the patches that are supposed to fix this? [1] http://lists.freedesktop.org/archives/intel-gfx/2015-April/065659.html Yes, I still need to re-spin that series with the comments addressed. Created attachment 115869 [details]
dmesg with log_buf_len=4M
This should be fixed in -nightly now. Test 5 cycles S3 entry and resume on SKL-Mobile, with drm-intel-nightly branch kernel：790a30_20150522 S3 is working normally, change this bug status to verified. Closing old verified. |
