What do you get for:

# btrfs insp dump-s -f /dev/
# btrfs insp dump-t -b 2629033574400 /dev/

The csum test doesn't complain so that suggests any corruption happens
before csum is calculated and written. It could be a bug, however we
also have a wanted transid that is lower than what's found (finds a
transid in the future). That's a bug no matter what, either the drive
firmware has some bug or Btrfs, and I would expect the firmware can't
be responsible for such a huge transid difference. But yeah maybe Qu
has an idea, also he knows about qgroups, I don't know anything about
them other than it can make things very slow. There are some fixes on
the way soon but it doesn't really help today.
