it looks similar to the problem I had.

Finally I was suggested to check/change the interrupt of the serial port
associated to the irda port.

What I had was that at booting time my irda port was recognized as
....
ttyS02 at 0x03e8 (irq = 4) is a 16550A
....

on the other hand, in my case 'findchip' utility found:

Found NSC PC87338 Controller at 0x398, DevID=0x0b, Rev. 1
    SIR Base 0x3e8, FIR Base 0x3e8
    IRQ = 9, DMA = 0
    Enabled: yes, Suspended: no
    UART compatible: yes
    Half duplex delay = 0 us


after changing the interrupt of ttyS02 from 4 to 9 with :

setserial /dev/ttyS2 irq 9

everything worked properly.

Hope it works for you too.

Ciao
Francesco
