Problem with Uart1 - uClinux

Hi, after successfully boot, I start to write some app on my uClinux
2.6.x on LPC2468. My application must communicate with some device on
ttyS1 which is second serial port on LPC. But when I open port with on
console with echo "Hello" >/dev/ttyS1, I get flood on console with
message:

serial8250: too much work for irq7
serial8250: too much work for irq7
serial8250: too much work for irq7

I try various configuration, with enabled and disabled Serial IRQ
sharing, with and without extended 8250 driver options and pretty much
everything that I think is related to serial ports. Also I try to
enable LPC serial support but then compile is not finished.

How I can resolve this?
