Thank you for taking the time to report this bug and helping to make Ubuntu better.
Am I right in understanding that this is a host kernel oops? My understanding of PCIe passthrough is that if you're passing through your sound card to a VM then the host kernel's sound driver should never crash, so this sounds like a kernel bug to me. My reasoning is that either the host kernel should not permit passthrough if the sound driver is using the card, or it should correctly reset the card before taking it over again afterwards. If this is wrong then presumably this is a qemu bug? For people who know more about this area, feel free to explain and reassign. But to make progress for now, I'm reassigning this bug to the kernel. ** Package changed: libvirt (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886234 Title: libvirtd Tainted: kobject_add_internal failed for emu10k1-synth-0-1 with -EEXIST, don't try to register things with the same name in the same directory.
