== SRU Justification ==

the 4.13 kernel in Artful.  Without this patch, servers with VMD enabled 
run into issues suspending and resuming.

Commit e2b1820bd5d0962d6f271b0d47c3a0e38647df2f is in mainline as of

== Fix ==
commit e2b1820bd5d0962d6f271b0d47c3a0e38647df2f

    PCI: vmd: Free up IRQs on suspend path

== Regression Potential ==
Low. This only affects one component of one arch and affects the non-typical use-case of suspending a server

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
