The patch looks innocent but it touches on other stuff that has changed a lot. For example, it adds cancel_delayed_work_sync() in the hdmi_poweroff() path. With my naive backport to vanilla-3.8, hdmi_poweroff() gets called within the context of that work item, and a work item trying to cancel_delayed_work_sync() on itself hangs. Reproduced just by unplugging the display once. I see that things have changed substantially in the ChromiumOS tree, for example this patch probably has some effect: commit 29ae0c6096395a96a597453271946fc7d8442b6e Author: Sean Paul <seanpaul@xxxxxxxxxxxx> Date: Thu Jun 20 17:24:12 2013 -0400 drm/exynos: Consolidate suspend/resume in drm_drv As this job seems bigger than anticipated and I don't have any Exynos hardware that can boot mainline, I think I might have to stop here, and hope that ChromiumOS guys upstream all this soon?
