1.Boot system.

Comment 1 Ander Conselvan de Oliveira 2015-05-13 06:32:02 UTC

Kernel command line is missing drm.debug=0xe, so the dmesg doesn't have debug information.

Comment 2 xubin 2015-05-13 07:42:24 UTC

Created attachment 115733 [details]
dmesg

Comment 3 xubin 2015-05-14 07:32:57 UTC

I can't find a good commit.

Comment 4 Damien Lespiau 2015-05-21 17:03:24 UTC

[drm:check_crtc_state [i915]] *ERROR* mismatch in dpll_hw_state.ctrl1 (expected 0x00000000, found 0x00000001)

Ander fixed this a few days ago.

Comment 5 ye.tian 2015-05-26 02:44:19 UTC

Tested it on the latest nightly kernel (7e83d3_20150526), this problem doest not exists.
So verified it.

Comment 6 Elizabeth 2017-10-06 14:29:59 UTC

Closing old verified.
