Xen developers,
After an upgrade of my Debian Jessie dom0 and domUs, my passthroughed
NIC stopped working.
This bug was probably introduced in Debian Jessie sometime
between 2015-12-30 and 2016-01-08 as 2015-12-30 as 2015-12-30 was the
last time I upgraded without any problems according to my dpkg.log.
This bug has also been reported to Debian Bug
(https://bugs.debian.org/810379), where I got instructions to contact you
directly.
The Debian Bug List is CC'd to keep the Debian Bug in the loop.
I created a new jessie domU (named "bug") and tried to passthrough some
PCI devices and found that both USB3 host controller and tg3 NIC generated
these lines in domU dmesg:
xen:events: Failed to obtain physical IRQ 31
xen:events: Failed to obtain physical IRQ 32
xen:events: Failed to obtain physical IRQ 33
And from the dom0 "xl dmesg":
(XEN) mm.c:812: d13: Forcing read-only access to MFN fbff1
(XEN) mm.c:812: d13: Forcing read-only access to MFN fbff1
