libvirtd tried to assign the USB controller to a VM, and the USB controller was already attached to the driver (xhci-pci) in dom0. The bug was triggered while the driver was detaching itself.
Try one of the following: - Temporarily detach the USB controller from the VM. - Blacklist the xhci-pci driver in dom0. (create a .conf file with line "blacklist xhci-pci" in /etc/modprobe.d) On Thu, Nov 18, 2021, 7:57 AM Peter Funk <p...@artcom-gmbh.de> wrote: > In a QubesOS 4.0 dom0 terminal I've tried the command:: > > sudo qubes-dom0-update kernel-latest > > and discovered afterwards my Laptop reboots due to a kernel null > pointer reference during boot when I try this kernel. > The stable kernel works fine though. > > I've tried to make a photo of the error message (see attached > .jpg file).
