--- Comment #36 from Ali Abdallah <ali.abdal...@suse.com> --- (In reply to Hans Petter Selasky from comment #26) The issue is that ioctl thread to get the media status, which basically started by userspace races with ue_tick_task. And I finally know why. The usbd_do_request_flags called releases the lock and then later acquire it (see the code). So, an ioctl waiting on the same lock will be executed together with ue_tick_task (because they aren't executed from the same thread), causing the race observed here and basically breaking all usb ethernet devices. I will shortly attach a patch to Sync ioctl/tick media status changes. -- You are receiving this mail because: You are the assignee for the bug.
