your lspci output to the bugzilla
(https://bugzilla.kernel.org/show_bug.cgi?id=72681). Maybe you
could attach the biosdecode info there, too, and we could see if
there's a way we can make this easier.
ok

everything.
bfsort : because, maybe, for a bfsort it must assign a number to each
bridge at the same level before inspect the next one.
noacpi : in order to scan independently from BIOS information
The result is always the same (empty buses are not enumerated).
Thank you :)

There was not any kind of protection against carrier driver removal.
