--- Comment #17 from Jean-Sébastien Pédron <dumbbell@FreeBSD.org> ---
Hi!

I have a hard time to follow between the mailing list thread and this problem
report, so let me try to rephrase:

1. There is a panic in pseudofs because the radeon driver wants to declase two
entries with the same name.

2. It looks like this double attempt comes from the fact that the same code
path is executed twise during init.

The problem appeared between commits 9b2a503a1179 and 6c3a4b5f9b7b in
freebsd-src HEAD.

Am I correct?

About the panic, it looks like it has been addressed by a commit from kib@:
https://cgit.freebsd.org/src/commit/?id=e9897199576a40360440aa4d2aa48d61c4010f11

That dosn’t change the fact the initialization is apparently called twice.
However I can’t find the dmesgs that are mentionned during the discussions
where the dump_stack() traces appear, demonstration the two inits. Could you
please attach these dmesgs here?

Thank you!
