I'm not sure which commit you are referring to, but the one which causes
this type of failure is:

  c3164d2e0d18 ("PCI/MSI: Convert pci_msi_ignore_mask to per MSI domain flag")

which is fixed by

  3ece3e8e5976 ("PCI/MSI: Handle the NOMASK flag correctly for all PCI/MSI backends")

i.e. this pull request.

TBH, and I know this is not your fault, this report page is a
masterpiece of bad engineering. It contains tons of useless information,
but fails to provide the most important basic data:

  1) There is no date of the failure

     Am I supposed to reverse engineer this out of this horrible user
     interface?

     I haven't even found a way to figure it out within a reasonable
     time. I just gave up.

  2) There is no useful reference to the actually used source tree and
     commit

     v6.13-rc7-16083-gc13edfd29c29 is _NOT_ a helpful reference as it
     suggests that this is a 6.13-rc7 based tree, but the log file says:
     Linux version 6.14.0

     sasha-linus-next at least gives a hint where to rumage, and 100
     clicks later I'm able to see what this is actually testing.

Seriously?

Thanks,
