Bug#897255: linux-image-4.15.0-3-amd64 - BUG: unable to handle kernel NULL pointer dereference at 0000000000000258
Package: linux-image-4.15.0-3-amd64
Version: 4.15.17-1
Dear Maintainer,
after shutdown of my four VMs for backup, the start of the second VM with PCIE-Passthru (Digital Devices GmbH Octopus DVB Adapter) with
virsh start command hangs. Reboot hangs too and only a hard reset or <sysrq b> helps.
