nvmecontrol updates firmware just fine, though.

What's supposed to happen is that the temperature climbs slowly enough
that there's a chance for it to kick in. It might be thermals, but I'd
expect
at least some indications that it's thermal. Heat sinks are cheap enough,
if it's really thermal. log page 2 has the temperature.

How often does the reset happen? A firmware upgrade might solve that
problem if they are older. There might just be a bug that causes the
firmware
to 'trap' and it takes several seconds for the SoC / controller to reboot.
