I have already reported this regression against mainline 6.18-rc2, see here: https://lore.kernel.org/all/a40caf8e-58ad-4f9c-af7f-54f6f69c29bb@googlemail.com/ When I revert this patch from 6.12.55-rc1, the issue goes away, just as in mainline. I'm still going to test 6.17.5-rc1 too and report back, but I guess it will be just the same.
