MSI error when reloading iwlagn module
Hi,
With a fairly current kernel + xen, I''m seeing this if I rmmod iwlagn
and try to reload it:

[PATCH v2] AMD/intremap: Prevent use of per-device vector maps until irq logic is fixed
...issue by failing the hypercall, but
is not acceptable IMO. One logical way to fix the issue would be to reassign
one of the irqs to a different vector, but that requires waiting for another
interrupt, and trashes the PCI device''s used_vector table.
The best solution I can see is to have create_irq() know about which PCI
device the irq belongs to, but I cant find a nice way of making this
information available.
George: This patch should go into xen-4.3 (as well as being backported) as it
is specifically to work around a regression caused by XSA-36
Changes since v1:
* Correct stupid mistake...
