--- Comment #1 from Vladimir Kondratyev <wulf@freebsd.org> ---
The ig4 is not fully support ddb yet.

There are missing parts:

1. It must skip sx_lock acquiring/releasing under ddb(4)
2. Under ddb(4) instead of acquiring of sx_lock it must check for already
running I2C xfer and terminate it if exist before starting of new one.
