Song Liu, what's the status here? I aware that you fixed with quite a
few regressions recently, but it seems like resolving this one is
stalled. Or were you able to reproduce the issue or make some progress
and I just missed it?

And if not, what's the way forward here wrt to the release of 6.8?
Revert the culprit and try again later? Or is that not an option for one
reason or another?

Or do we assume that this is not a real issue? That it's caused by some
oddity (bit-flip in the metadata or something like that?) only to be
found in Dan's setup?

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
