Ok. That makes sense.

Sure this bug is the one you wanted to point me to? "Spontaneous Reboots"

Yes, that does look likely.

So if I understand correctly, something is marking SYSTEMD_READY=0 -
either rightly or wrongly - and this value doesn't change even though
the device does appear to be ready.

Wonder if there is anyway of manually invoking the udev builtin and
checking its state?

IMPORT{builtin}="btrfs ready $devnode"

I also note that when it does work /dev/sdb1 still has ID_BTRFS_READY=0
and SYSTEMD_READY=0 and /dev/sdc1 doesn't have that attribute. I guess
/dev/sdb1 doesn't matter, as the reference in /etc/fstab is to /dev/sdc1
however it seems kind of confusing.
