The only good news is, that corruption is in extent tree. Thus you can still salvage your data in RO mode. > > It always occurs some minutes after booting, sometimes even seconds > after booting.

Please run `btrfs check` on the unmounted fs. (Since you're already using Arch, using latest arch iso looks like the best solution if it's your root fs). If feel like to have a adventure, you could try `btrfs check --init-extent-tree` after posting the `btrfs check` result. It can be very slow, and may not always fix your problem. > > I attached some more output of dmesg.

Arch's kernel is mostly upstream, which is mostly good for btrfs usage, so is its btrfs-progs version.
