I've updated the log[3]. There is no crash per se here, just the
system becomes unresponsive. It looks like some watchdog timer goes
off (NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s!) and it
becomes usable again for a few seconds before it locks up again and
the process repeats.

100, maybe more.

The full story here is that my file system was becoming full so I was
using baobab to investigate what was eating my storage. While baobab
was scanning my disk, I happened to be deleting a few things and
running `btrfs balance start...` (as you can see in[3]), but I don't
think the lockups are related to any of that because I saw them
previously with baobab when I was not doing any balance.

I've since removed all of the btrfs subvolumes created by docker and
everything is working fine again with no lockups (so I can't recreate
this anymore).
