Public bug reported:
[Impact]
c4.large instances are stuck at boot with kernel 5.15.0-15.15.
[Test case]
Simply deploy a c4.large instance and install the latest jammy kernel
(5.15.0-15.15).
[Fix]
It looks like the offending commit is the following:
02c70033b98b ("PCI/MSI: Mask MSI-X vectors only on success")
Reverting the commit fixes the problem.
[Regression potential]
It looks like the commit was fixing a potential breakage with broken
Marvell NVME devices, so we may see crashes in presence of these
devices. However, reverting the commit we are simply restoring the
previous behavior, so potential regressions should be limited to these
broken devices.
** Affects: linux (Ubuntu)
