When I attempt to start a server with chrt the host system panics. I can start a uml in normal (other) scheduling, and then change it to RR-Scheduling and it works fine, until I try to stop the uml... then I get the same kernel panic. I'm using the skas-3 patch on a 2.4.21 kernel, and 2.4.21-6um. If you need the specific output of the kernel panic, I can get it... Just as a related question... how would different scheduling the different 'threads' of the UML effect performance? As far as I know.. the first 'linux' process actually does all the work and the extra processes are for the different IO the UML does, eg network, block devices etc? Would increasing the priority of the IO over the priority of the main process have an effect on network performance for example?
