[Kernel-packages] [Bug 1763594] Re: xhci hangs; reset results in NULL pointer dereference
I reproduced the same(?) issue by passing by passing an usb controller to kvm.(https://www.redhat.com/archives/vfio- users/2018-February/msg00030.html) When I shut down the virtual machine and try to start again it always fails. Tested your kernel and still the same issue. Hope this helps. ** Attachment added: "before.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763594/+attachment/5157190/+files/before.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1763594 Title: xhci hangs; reset results in NULL pointer dereference Status in linux package in Ubuntu: Incomplete Status in linux source package in Bionic: Incomplete Bug description: Now and then, my xhci bus will hang, resulting in these kinds of messages in dmesg: [252220.002102] xhci_hcd :00:14.0: xHC is not running.
