Yes, one small difference is that 2.0.36 writes
tty03
and 2.1.125 writes
ttyS03

My device is called /dev/ttyS3 but it doesn't matter.
Same interrput values do work okay with 2.0.36. What shall I do to make it
work under 2.1.125?

Anyway, I have no setserial command during boot (I've explicitely purged
those since they just set the same values, but using /dev/cua*).

Thx
