Note that this driver has the same issue as the vanilla atmel serial: it
may loose characters in case of high irq latencies.

Anyway, could you post the two kernel configurations, the one which
works, the one which does not work?

Other than that, I guess all you can do is try and debug the driver,
starting with the serial irq and trying and understanding how it gets lost.
