I encountered this with 4.4.167 - dump is up at https://gist.github.com/lisa/972b27c561e1fb58a6d268d24de88a81#file-crashlog-txt |

Other chip, other way of replication but the same error with this rockchip64 kernel 4.4.180: https://dietpi.com/phpbb/viewtopic.php?f=11&t=6062 |

Assertions reports are split into two parts, the exact file and location of the condition and then the stack trace printed from btrfs_assertfail(). This means all the stack traces report the same line and this is what's typically reported by various tools, making it harder to distinguish the reports.
