Hm, interesting issue.
But I'm not convinced that it's caused by the SSB port, though.
What the SSB port essentially does is modifying small areas in the
init and exit paths. The modified things in the TX and RX hotpaths
are really tiny and trivial. TX timeout sounds like something in the
TX/RX paths is going wrong.
But anyway, maybe I got something wrong.
I'll run some burn-in tests on it now.
