I'm way out of date on this, but that patch looks like it was committed into the Linux kernel in Mach 2015:
https://github.com/torvalds/linux/commit/227a4fd801c8a9fa2c4700ab98ec1aec06e3b44d ... which would suggest that it would have appeared "in the wild" with 3.19.2 or thereabouts? Even if my timeline isn't completely accurate, and if that patch fixes the problem, then it should be ancient history by your 4.4.0 kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313279 Title: xHCI host not responding to stop endpoint command To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1313279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
