Issue #447 reports random pulses on the DAC outputs after a soft or hard reset.
This can be fixed by using different initial DAC output buffer values on stabilizer and cycling the !CLR pin of the DAC.

Note: this software patch also needs some hardware modifications to work (adding pullups on DAC !LDAC pins, see #447)

Ok.
Run cargo fmt --all over it to make the style checker happy and this is good to go.
