Fiasco on real hardware

2.3.5-r2

hmm, sorry, I can't remember...

I tried it again today by producing lots of output by simply "cat /dev/urandom",
but that didn't reproduce the error. I also tried to recompile the application which
led to the error yesterday, but now it went through smoothly, so its probably been
just a strange coincidence

Thanks anyway,

Marcel
