Thanks for report. I assume that the issue is because above patch removed 'suspended' vari= able for checking the suspend status in runtime so I revived it. I'm not sure that the change could resolve the issue. Could you test it with the change again? I have no Exynos5800 Peach Pi board. :( =46or this, I pushed it to below exynos-drm/for-next branch, https://git.kernel.org/cgit/linux/kernel/git/daeinki/drm-exynos.git/co= mmit/?h=3Dexynos-drm/for-next&id=3De84f43e2b2c3388694b0b3a58c2c4447f1fb= ae7c If the issue is resolved by the change then I will modify other patches= for DECON series. And if really so, there may be a corner case we missed. Thanks, Inki Dae >=20 > Best regards, >=20
