When used with RTAI, rtcfg is the module that starts RTAI's system timer on load. If something is wrong with that timer subsystem, maybe also if the timer is already running, that oops can be the result. Should be discussed with RTAI folks. maybe i don't need this module because i only need realtime acces to my nic (rtl 8139) without any mac discipline. Is there a tutorial which describes how to use configure only the realtime nic driver? See Vinzenz' reply.
