Hm, could you provide full dmesg output please with
"dyndbg=file drivers/pci/* +p" added to the kernel command line
(the double quotes need to be included on the command line).
Be sure to set CONFIG_DYNAMIC_DEBUG=y in .config when compiling
the kernel.

Ideally both for a non-working kernel such as 6.12.73 and for a
working kernel such as 6.12.63.  That should make it easier to
root-cause the issue.

Thank you!
