This bug is awaiting verification that the linux- oracle-5.15/5.15.0-1006.8~20.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[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.
