I just checked again with todays snapshot - the crash is still there...
Having a revision 1.3 here, appearantly leaving the system alone keeps it 
healty, but if you have high sysload+recording+playback going on - that way 
the chips are stressed more i think (my card has an extra fan) - the crash 
happens soon.
First one get's outcommand errors (resulting in long keay-reaction-times in 
playback mode) and error waiting command idle, later vdr-buffer usage goes to 
100% and the ARM crashes. After watchdog reset the driver reloads but fails, 
because if some other program has still open /dev/video the necessary modules 
can not be realoaded and stay in kernel.

PS: I verified - the one and only call to SetPIPs is with all zero's... maybe 
one should call that again for some reason?

PPS: my kdvb-* threads are always low on CPU-usage...
