Hi Mikhael,

Your problem is likely related to the fact the sa11x0 serial driver is
poorly written. The standard 16550 driver should work fine, however.
Could you try the (untested, because I can't anymore) attached patch, which
just switches the driver, to see if it makes a difference ?

Thanks,

Olivier
