solves system lock-ups by making all processes non-realtime
Das_Watchdog is a general watchdog for the Linux operating system that should be run in the background at all times to ensure a realtime process won't hang the machine. . Das_Watchdog is inspired by the rt_watchdog program from Florian Schmidt, but has some improvements over it: * It works with 2.4 kernels as well as 2.6. * Instead of permanently setting all realtime processes to run non-realtime, das_watchdog only sets them temporary. * When the watchdog kicks in, an X window should pop up that tells you whats happening (just close it after reading the message).
