Public bug reported:
SRU Justification
[Impact]
Hypervisor only allocates interrupts to happen on a single physical GPU,
which can lead to CPU soft locks when using PCI NVME under heavy load.
[Test Case]
Microsoft tested
[Where things could go wrong]
Hypervisor PCI driver may not load correctly. Patch did not apply
cleanly and could lead to merge conflicts once the upstream patch is
pulled in.
