MSI badness in xen-unstable
Hi,
I''ve been trying to boot stefano''s minimal dom0 kernel from
git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git
2.6.36-rc1-initial-domain-v2+pat
On xen-unstable, I get the following WARN_ON()''s from Xen when bringing
up the NIC''s, then the machine hangs forever when trying to login either
over serial or NIC.
(XEN) Xen WARN at msi.c:649

[PATCH 0/8 v4] PCI: Linux kernel SR-IOV support
Greetings,
Following patches are intended to support SR-IOV capability in the
Linux kernel. With these patches, people can turn a PCI device with
the capability into multiple ones from software perspective, which
will benefit KVM and achieve other purposes such as QoS, security,
and etc.
