Subject: "PCI/MSI: Mask MSI-X vectors only on success" (boot problem on c4.large)
Date: Fri, 7 Jan 2022 18:32:40 +0100	[thread overview]
Message-ID: <Ydh5OCudJKz5Y7jc@arighi-desktop> (raw)

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
