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
