Do you have any logs? Also when you have a suspicion that it was caused
by hardware, what's the SSD type? If you'd like a more interactive
discussion please come to the libera.chat #btrfs channel, there are
people with a lot of experience and knowledge about buggy hardware. In
case it's a btrfs bug we'd be interested to know at least something that
could help to narrow it down.
