I am compiling some packages with poudriere on 13-current kernel. I
noticed some strange messages printed into the terminal and dmesg:
lock order reversal:

Poudriere doesn't really report any problems:
# poudriere status

Are those the debug messages that aren't visible on non-current kernel
and should they be reported?
