We need all the luck we can get, In March 2004 when we were testing the calif. We found that a majority of our problems with linux was the fact that some of the custom drivers we wrote do not get a chance to run. The other processes take up most of the CPU time.
Has anyone here used / experienced libRT ?. We have been looking at that for sometime now.
