Xen 4.6.1 (testing repo) breaks PCI attachment

[HW42]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Hi,

with Xen 4.6.1-15.fc20 (which got recently uploaded to the testing repo)
VMs with attached PCI devices don't boot anymore (at least on my
machine).

When I try to boot a VM with attached PCI devices it crashes
immediately. Attached the xen dmesg log of a crash.

Both dom0 and the VM are running the 4.1.24-9.pvops.qubes kernel.

HW42

PS: Do you prefer reports regarding problems with testing packages on
qubes-users or qubes-devel?

Thanks for the report! I think for something like this, qubes-issues
might be best (but it's up to Marek's preference). For example, how
closely is your report related to this existing issue?

https://github.com/QubesOS/qubes-issues/issues/1659

If you think it's close enough to be posted as a comment on that
issue, please feel free to do so (or I can do it for you). If it's too
different, then feel free to open a new issue (or I can do it for you).

This is not really related. My problem is PV related (didn't tested
HVM). And most notably this is a direct regression of the update to xen
4.6.1-15.fc20. xen 4.6.0-13.fc20 works fine.

If you like to have a GitHub issue then please create one as I currently
don't have a GitHub account.

Thank you, HW42

Exactly the same versions works fine for me...

Do you have anything in console log of that VM? If not, try starting it
in debug mode (this enables earlyprintk).

Better qubes-devel (moving there).
