Title:
  [Azure] [NVMe] cpu soft lockup issue when run fio against nvme disks

Status in linux-azure package in Ubuntu:
  Invalid
Status in linux-azure source package in Kinetic:
  Fix Committed

Bug description:
  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.

  Kinetic will get this patch via stable updates.

  [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.

  [Other Info]

  SF: #00346549
