Subject: Link training error with 4.3.rc2+
Date: Fri, 25 Sep 2015 11:01:14 +0100	[thread overview]
Message-ID: <56051B6A.80502@linux.intel.com> (raw)

Hi,

With 4.3.rc2+ I am seeing below WARN followed by a link training error 
when the login screen comes up on ubuntu. Once I get the error log in 
console screen goes blank and stays that way. I am also not able to get 
to virtual terminal.

The panel connected is eDP.
