not without spending more time I can effort ATM and without finding a
better test procedure (currently 1-2h per run).

I'm not convinced that it is an ext4 bug. The corruption may also occur
when the data is written to the nvm. The hardware (chipset-less AM5
mainboard) is quite new, the only vendor (Asrock) probably does not care
about Linux and maybe AMD did not tested is carefully enough. Thus,
there a quite a lot of changes from 6.3.5 -> 6.3.7 that could cause the bug.

I'll try to find out more next week (other ways to reproduce the error,
other hardware, ...), especially whether it is a  more general issue or
hardware specific.

Regards Stefan
