Can confirm that is still an issue with kernel 4.11.3 for both the Dell TB15 and TB16 docks.

I wonder if the microsoft docks that have been recently added also exhibit these same issues: https://github.com/torvalds/linux/commits/master/drivers/net/usb/r8152.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663975 Title: XHCI errors causes dock USB and network adapter dropouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663975/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
