Bug#856733: linux-image-3.16.0-4-amd64: Xen guest has multiple stack dumps, ending with spontaneous reboot
Package: src:linux
Version: 3.16.39-1+deb8u1
Severity: important
Dear Maintainer,
after installing the latest linux-image update, one of my Xen guests suddenly logged multiple
kernel stacktraces. The initial one was this:

The system now appears slightly "upset" - an rsync to copy some files from it fails with "Corrupted MAC on input", so
it is not working normally.
The system has been running for a couple of years, and I have not seen this error before. There are several other Debian
Linux Xen guests running on the same hypervisor, these have not shown any symptoms like this.
