Wouldn't hurt to update though. There have also been slight updates to the ctxsw fw in kernel 4.4, so you could try 4.4-rc8 and see if the issues remain. (Also the driver got a substantial refactor/rewrite in kernel 4.3.) Either way, please check on latest to see if issues persist.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
