By the way, the issue seems similar with R-Car environment though :) http://thread.gmane.org/gmane.linux.kernel.stable/175457/focus=140699 and fix patch for it: http://thread.gmane.org/gmane.linux.kernel.stable/177524 Best regards, Yoshihiro Shimoda > either with this patch, then please let me know.
