Subject: [4.4-rc1][Regression] drm/i915: Check live status before reading edid
Date: Wed, 24 Feb 2016 16:38:35 -0500	[thread overview]
Message-ID: <56CE22DB.6050108@canonical.com> (raw)

Hi Sonika,

A kernel bug report was opened against Ubuntu [0].  After a kernel
bisect, it was found that reverting the following commit resolved this bug:

commit 237ed86c693d8a8e4db476976aeb30df4deac74b
Author: Sonika Jindal <sonika.jindal@intel.com>
Date:   Tue Sep 15 09:44:20 2015 +0530

    drm/i915: Check live status before reading edid



The regression was introduced as of v4.4-rc1.

I was hoping to get your feedback, since you are the patch author.  Do
think increasing the number of tries in intel_hdmi_detect() is worth
trying?  Do you think gathering any additional data will help diagnose
this issue, or would it be best to submit a revert request?
    

Thanks,
    
Joe
