@jsalisbury I have tested some vanilla kernels 4.13.x that have the same problem. See my paste here which seems like the exact same problem, which I pasted in reply to someone else's with similar/same problem https://gist.github.com/anonymous/d1cfe9ef5ebef0f96bb8d9ac451140f0
But since 4.13.11 (also tested 4.13.12, 4.13.15 and 4.13.16), it works fine. My kernels are just vanilla plus the AMD NPT patch and acs_override. And RE the v4.14 testing suggestion... beware of a data corrupting bug in the block layer before v4.14.2, and avoid testing those, especially if you use bcache and btrfs which trivially gets corrupt (the bug: https://www.spinics.net/lists/linux-bcache/msg05290.html and the fix: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=62530ed8b1d) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1733901 Title: /build/linux-KM2a5S/linux-4.13.0/drivers/usb/core/devio.c is crashing on kvm / qemu machine bootup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1733901/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
