Hi Stefan,
I'm experiencing some boot problems on c4.large instances on AWS with
this commit applied (system stuck at boot - no oops or panic, just
stuck):
83dbf898a2d4 ("PCI/MSI: Mask MSI-X vectors only on success")
If I revert this commit the boot completes correctly (found doing a
bisect).
I'm using a 5.15.12 kernel. Let me know if there's anything I can do to
better track down the issue. For now I've just reverted the commit.
Thanks,
-Andrea

Sorry, I don't have a good idea what might go wrong here. Perhaps Thomas
has some thoughts on this?
Thanks,
Stefan
