I just encountered this bug again in cosmic with kernel 4.17.0-041700rc1-generic. Definitely not fixed in 4.17.
Note that with kernel 4.15, the xhci hang occurs too, but then I can reset the bus without causing a kernel Oops. I'll attach the Oops for 4.17 ** Attachment added: "kernel oops" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763594/+attachment/5155455/+files/oops.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763594 Title: xhci hangs; reset results in NULL pointer dereference To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763594/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
