Hello Arindam, There is a bug report[0] that you created a patch[1] for a while back. However, the patch never landed in mainline. There is a bug reporter in Ubuntu[2] that is affected by this bug and is willing to test the patch. I attempted to build a test kernel with the patch, but it does not apply to currently mainline cleanly. Do you still think this patch may resolve this bug? If so, is there a version of your patch available that will apply to current mainline? Thanks, Joe [0] https://bugs.freedesktop.org/show_bug.cgi?id=101029 [1] https://patchwork.freedesktop.org/patch/157327/ [2] http://pad.lv/1747463
