Hi guys.
I think 4k LBA - in my case on WD_BLACK SN850X - is
something Fedora's default BTRFS cannot handle.
My Fedora 43 clean installation, number of them, crashes
badly that way, but when I, at another subsequent
installation eventually used ext4 instead, then ! ...
problems went away.
Very same NVMe disk - but with 512b - did not give any
problems and I've had it for ~3yrs.
thanks, L.
