Serial Port fourth instance

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Hello All,
I am using PCM-6892 board (VIA C3 processor) ,which is having builtin four
COM port.
By default only three Instances of COM port(Device driver ->
serial->Com16550) are there in platform builder .For forth Port I added one
more instance in Platform.
My problem is that, after running for some time forth port stops
responding.It happens randomly .I am not sure whether it is related with
Platform setting or not.I am doubting on "Ranges" in serial port 3 & 4
because both are same.I changed platform setting in platform.reg as:
