PCI/MSI: Boot issue on X86 Laptop 6.18-rc1

PCI/MSI: Boot issue on X86 Laptop 6.18-rc1

[Oliver Hartkopp]

Hi all,

my Lenovo V17 Gen 2 (i7-1165G7) does not boot since commit

54f45a30c0d0 ("PCI/MSI: Add startup/shutdown for per device domains")

from the beginning of the 6.18 merge window.

I've checked the discussion about the original patch "[PATCH v2 2/4] 
PCI/MSI: Add startup/shutdown for per device domains" here:

https://lore.kernel.org/all/qe23hkpdr6ui4mgjke2wp2pl3jmgcauzgrdxqq4olgrkbfy25d@avy6c6mg334s/

where a fix has been suggested (which was later applied) that doesn't 
help on my machine. So the Linus' latest tree 
6.18.0-rc1-00017-g5a6f65d15025 still does not work.

I was pretty lost when trying to follow the PCI quirk discussion about 
"[PPC] Boot problems after the pci-v6.18-changes" here:

https://lore.kernel.org/linux-pci/4rtktpyqgvmpyvars3w3gvbny56y4bayw52vwjc3my3q2hw3ew@onz4v2p2uh5i/T/#ma4425fd40ec041dcda2393a55bca5907887c2b52

Any idea how I can support you to make my machine boot again?

Thanks,
Oliver

That fixed it!

I should have searched for the problematic commit message more 
intensively once I found it myself :-)
