Hi all,

when trying to btrfs send a snaphost I get this in dmesg:
[8614395.539466] BTRFS error (device sda1): did not find backref in
send_root. inode=673755, offset=131072, disk_byte=25730310144 found
extent=25730310144

scrub reveals no errors
scrub status for bb8094e8-a7b1-4c2d-854e-77a9921e6f7e

        total bytes scrubbed: 67.49GiB with 0 errors

Is there something else that I might try to get this work?
