There was no interrupt (short or long pulse) when I turned off the monitor connected to the dock. The display comes up fine after I turn it on. But, with Jiri's configuration, the dock seems to send a long pulse indicating a dock unplug. Therefore, the connectors get destroyed. I don't think the kernel is doing anything wrong here. We'll need more debug information to confirm that the userspace isn't able to deal with new connectors.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
