Hmm, no it hasn't. I think there is either a controller or device initialisation problem, and it might be a race. On power-on, one of two different things will happen after the Mac startup chime:
1. Usually, there will be along pause (30sec? 1min?), some random display corruption, then boot proceeds normally. 2. Boot proceeds immediately. In the case of #1, the following is printed to kern.log: > xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command > usb 2-3: device not accepting address 14, error -62 Also, when case #1 occurs, then this suspend/resume issue manifests itself. When case #2 occurs, those messages are not printed in kern.log, and this suspend/resume issue does not occur. I have just had both occur in quick succession with both the current 4.2 kernel in wily, and 4.4-rc2 from the mainline kernel PPA. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1507472 Title: XHCI controller causing MacbookPro12,1 to resume immediately after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1507472/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
