PCI bridge to bus boot hang at enumeration; works on v6.0, stops working at v6.1-rc1 upto v6.2.-rc1

Hello there

1. Happy holidays ;)
2. Please see: https://bugzilla.kernel.org/show_bug.cgi?id=216859

With Kernel 6.1-rc1 the enumeration process stopped working for me,
see attachments.

The enumeration works fine with Kernel 6.0 and below.

Same problem still exists with v6.1. and v6.2.-rc1

Please see attachments.

Best
