I still consider this as a workaround for a driver bug in nuoveau/optimus. IMHO a better fix would be to change the way how drm_kms_helper_poll_init() works: when called it would not enable the polling as it does, but drivers would need to call poll_enable() if they want the polling to be active. Tomorrow I can create a hack patch for this on top of 4.10-rc2 if you are willing to give it a try. It is still awkward to wait with the work for 1 sec, it is better than the 10 sec, but still it does not feel right. In any way, I will prepare this patch as well for sending as a quick workaround.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
