I have ffado/jack running with my Mackie Onyx 1220i.

It has been running great for months now....but suddenly, after hours of working fine, I get a catastrophic failure when I try to start jack.

Nothing (literally nothing) has been installed/updated recently, so I'm not sure what could be causing the sudden failure.
