So today, I synced with Linus' master branch again:
37816488247d ("Merge tag 'net-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net")
and applied your fix on top of it.
I can boot, but I get this splat. Looking at the call trace, it seems
it's still related to pci, but different issue. The call trace is also
different from the previous one.
Let me know if you have something for me to test.
