I should add that I have reproduced this even after doing `mount -o
clear_cache /dev/... /mnt/...`, unmount, remount with `-o
space_cache`. After the machine lockup and rebooting there are the
warnings of the form:

> [ 117.288248] BTRFS warning (device dm-0): block group 694165700608 has wrong amount of free space
> [ 117.288253] BTRFS warning (device dm-0): failed to load free space cache for block group 694165700608, rebuild it now
