Also, if the system crashes, it can be helpful to catch the oops message it hopefully generates. Best done via a serial kernel console, alternatively via netconsole. Maybe there is an IRQ conflict between the rt2500 and some Linux driver. Check the IRQ number it uses and compare it to /proc/interrupts. The RTnet driver should detect and report spurious IRQs, but I'm not sure if RTAI handles this properly.
