These are some of the DPC fixes which help in handling some of the failure cases of DownPort Containment events. Without these, recovery from DPC event fails and NVMe endpoint is not accessible for some of the scenarios.
Upstream kernel patches to be included into Ubuntu 22.04 SRU and into Ubuntu 20.04.5:
PCI/portdrv: Enable Bandwidth Notification only if port supports it
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.17-rc6&id=00823dcbdd415c868390feaca16f0265101efab4
