Bug#844446: linux-image-4.8.0-1-amd64: Fails to boot on qemu/kvm
Package: src:linux
Version: 4.8.5-1
Severity: important
Dear Maintainer,
I am running a stretch VM on a jessie KVM/qemu/libvirt host. After the
upgrade to 4.8.5 the system does not boot anymore. Booting the 4.7 kernel
works.
If I start normally, systemd hangs starting some early units (like
keyboard layout). The console log from 'emergency' boot is attached and
shows various oopses and backtraces.
The qemu command line on the host is (with some ids replaced):
