Hello, What is the best way of converting an existing device driver to work under a real-time kernel? A device driver provided for a special serial card (Curtiss Wright SL240 sFDFP card http://www.cwcembedded.com/products/0/1/461.html) works under vanilla Linux (SLES SP10 SP2 kernel 2.6.16.60-0.21-smp), but compiling the driver under the real time kernel (2.6.22.19-0.14-rt) the system locks up and crashes. The rt kernel is being used to write large amounts of data from the serial card to disk and testing has found the rt kernel has the best consistent write performance. I have gone back to the supplier and they are not interested in developing a real time version of the driver. So I am trying to modify the driver myself. The driver code can be provided if anyone wants a look (released under GPLv2). Any assistance would be useful.
