It just finished. Here was the remaining output:

[5/7] checking csums (without verifying data)  (0:30:31 elapsed, 5327794 items checked)
[6/7] checking root refs                       (0:00:00 elapsed, 18 items checked)

I didn't see anything bad except the mass of "failed to load free
space cache for block group …". Is there anything that is safe to
try without newer kernel and btrfs-progs?

Thanks,
