Subject: serial8250: too much work for irq73

Hi List

I am running into issues , when using ttyS1 on a heavy loaded 
application. It trys to send and recieve around 60bytes every 100ms with 
57600baud.  There is a PIC Microcontroller attached on the otherside 
which immidiatly returns the data when requested.

After some hours , the kernel starts to flood with the above messages 
and the system gets into an unusable state.

i am running 2.6.35.9 ( released from isee.com ) on their Igep Module ( 
arch igep0030).

What would you guys do ? Anything i can provide you to help here ? Its 
really a major issue for us and showstopping an important release.

Thanks in advance for any help or suggestion

Regards Rob
