--- Comment #11 from Warner Losh <i...@freebsd.org> --- yea, this is a feature of cd that polls for new media all the time. Usually it's not there. da has the same problem with removeable devices. We really should only do it when the device is OPEN. Who cares if the media changes when we're not using it. You can filter the devd events if you don't want them. They are harmless other than filling unfiltered logs. It is kinda useless activity and I'm not sure what the point really is (other than to re-taste the device when the media changes). Since these CDs don't support the "push" notifications when media changes in these virtual environments, we fall back to polling. You can disable media checking by setting kern.cam.da.poll_period=0 and kern.cam.cd.poll_period=0. -- You are receiving this mail because: You are the assignee for the bug.
