This error has got nothing to do with the internal flash so USB Boot Recovery won't help.
Can you try booting into volume read-only mode?

Tried booting into Volume Read Only mode from the boot menu and the boot process stops at the same point as a normal load, at right around 25 to 27%, and then displays the same btrfs_biomerge_bio_hook+a4 message.

Do you have a backup of your data?
- Kwilk6Dec 12, 2016Aspirant
Not all of it. I was using this NAS as a holdover for some data that was not being backed up until another NAS was ordered to store it.
Is this possibly a snapshot issue? Should I attempt to turn them off?

Turning off snapshots is not going to get the system out of this state.
Sounds like you should contact support. There would be some costs involved with looking into this. It could end up being a data recovery situation.
