Still happens with: 4.4.0-040400rc8-generic from the mainline PPA (there is a non RC 4.4 there, but it's older than RC8 so I used that instead).
These errors are reported now: > [ 11.924171] usb 2-3: device not accepting address 2, error -62 > [ 16.832609] usb 1-3: device descriptor read/64, error -110 Also, I worked out how to reliably reproduce the related issues - the long pause at boot, the errors above, and suspend immediately resuming if wakeups from XHCI are not disabled: Just do a cold boot, i.e. from power on. Warm boot show none of these symptoms. -- 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/+bug/1507472/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
