RTAI (3.0) works without any problem: all the examples run and I usually use it to generate and run code from real time workshop and everything is ok. The system crashes only when I try to run rtnet examples, so I suppose I'm doing something wrong when I load rtnet or when I install it. As I'm not expert in linux, maybe I do stupid mistakes and I can't see them... I followed all the steps I found in rtnet/README and I find problems when I use rtifconfig (always the same message that I don't understand : "ioctl:Inappropriate ioctl for device"). Did anyone else find my same problems and find a solution? Thanks, Marina

They would break the timing guarantees, but they should not crash your system! At least I'm not aware of any 3c59x-rt-related issues at the moment. So please check the lower level first.
