Anyone faced this trouble?
Well.... what I'm debugging are lockups after many packets transmitted
(followed by netdev watchdog; stmmac_tx_err() does not work for me, it
kills the device even when run from working state; ifconfig down/up
helps). 4.4 locks up in minutes to hours, 4.9 seems to work better
(but I believe I seen a lockup there, too; once).
So... probably different problem?
Best regards,
Pavel
