Have you tried isolcpu for the real-time? RTAI will reduce system responsiveness, but not by much if no real-time software is running. You should try booting into a generic kernel and seeing if the kmail problem persists. If you don't have a generic kernel, it's rather easy to build one with the help of google. Linux will tolerate many kernel builds on the same system, I think my desktop probably has a couple dozen by now. I think I scanned your message well enough to tell that you didn't do this yet. I think this is a necessary first step before you try to open a bug report. It may be helpful to d/l the kernel package for the r/t kernel from linuxcnc and look at the config. Eric
