Message-ID: <4D483062.9010809@mibtec.de> (raw)
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
