Package: linux-image-3.16.0-4-amd64
Version: 3.16.7-ckt25-2
Source: linux
Severity: important

Since a kernel update in early Januar 2016 xen pci passthrough stopped 
working.
There is already a bug report against the hypervisor in place (#810379) 
and a upstream report at xenproject.org which provides patches as well 
as at kernel.org (at least for 4.x kernel, 
https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.1.20).
The patches where created and tested against the current jessie 3.16 
kernel and I'm currenly testing those as well - so far it looks good.

For further information on how to reproduce this issue and the patches, 
I refer to the existing reports at:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=810379
http://lists.xenproject.org/archives/html/xen-devel/2016-02/msg00658.html

As those patches are accepted upstream, it should follow the debian 
rules for beeing fixable in stable.

Cheers,
Christian Schwamborn
