[Xen-devel] Fwd: [Bug 860175] Re: pci passthrough of snd_hda_intel or via usb to oneiric hvm breaks xen pvops drivers
Hi,
While upgrading my xen host & guests to oneiric, i seem to have
stumbled over a
problem in the xen subsystem for recent (3.0 & 3.1) kernels. What i
notice is that
the pvops disk driver fails during boot, when i use pci passthrough on
some
(not all) devices, i suspect what works is PCIe, and what doesn''t work
is PCI.
Disabling acpi, pci passthrough of some devices, or the xen pvops block
driver
seems to solve the problem.
For more detailed information see
https://bugs.launchpad.net/bugs/860175
I would have liked to submit this pr to bugzilla.kernel.org as
requested by the
ubuntu team, but that site does not seem to be online, hence i''m
reporting this
to linux-kernel and xen-devel mailinglists instead.
If there''s anything more i can do to help track this problem down, do
let me know.
Warm regards,
Mark.

This issue appears to be an upstream bug, since you tested the latest
upstream kernel. Would it be possible for you to open an upstream bug
report at bugzilla.kernel.org [1]? That will allow the upstream
Developers to examine the issue, and may provide a quicker resolution
to
the bug.
If you are comfortable with opening a bug upstream, It would be great
if
you can report back the upstream bug number in this bug report. That
will allow us to link this bug to the upstream report.
