Yikes. You'll have to report this upstream, but we'd appreciate a link when you do.

(In reply to Jeff Cliff from comment #3) > (i should clarify: rc6 does not do this, but rc7 does) While linux-next is for the brave, you could attempt a git bisect to help upstream.
i am willing to do a git bisect if someone can point me to where linux-next 's git repo is (and if it isn't github, which i do not have access to)

thank you i will get on that as soon as objdumping vmlinux finishes(been at it for like 2 days now but still going)
Ok, good luck. There's nothing for us to do here, as we don't patch linux-next.
i know y'all are 'not supported'ing this one but since Sam James asked: https://lore.kernel.org/linux-next/20230619204309.GA13937@willie-the-truck/ appears that someone else reported this 'upstream' (does this qualify?) before i got there ( my git bisect resulted in the right commit - a merge that according to the above thread broke something https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=70c94cc2eefd4f98d222834cbe7512804977c2d4 )

Thanks for letting us know
