Well... I'm still using i.MX6 with 5.14 and Krzysiek Wilczyński's "PCI:
Race condition in pci_create_sysfs_dev_files (can't boot)" patch (which
fixes the problem). It seems parts of this patch are now in mainline,
but most of it is still missing. So I guess the problem isn't fixed.
Perhaps because the DEC Alpha part of the patch is not yet ready?
Krzysztof?

Right, but they hadn't fixed the problem. 5.13 was released in June, and
I have started using the patch in August (apparently with pre-5.14
first, then with final 5.14).
