Greg, please drop this patch from both 5.10 and 5.15.

But this is already in released kernels: 6.1.53 6.4.16 6.5.3 6.6-rc1
I am going to send a fix to drop the check altogether.
We will be glad to queue up the fix as well when it hits Linus's tree, please be sure to tag it for stable backporting so we can get it in all locations.
But for now, being bug-compatible makes more sense, right? Or is this really critical and should not be in these kernels now?
According to that e-mail, the patch breaks booting for some systems, so if it would be possible to avoid it...
I've sent a fixup patch which removes the BUG_ON altogether, and referenced the patch that broke booting in the Fixes tag. But I don't know how long it will take to hit Linus' tree, it may take several weeks.
