actually, I am glad to hear that, silly it sounds, as I was getting paranoid
something was wrong with my machine. :)

I got rid of rtirq and das-watchdog entirely. after that, the machine didn't
lock up for at least as long as Robins session, ~45 mins, but the in the
middle of some session I would have liked to keep the recording of, dang..

it seems for me to be related to audio, as it only froze when doing some
more tough processing/synthsis with SC.

yes, one can't do anything about this. I'm too lazy to do the kernel
debugging thing, so I'll rather hunt for a combination of patches & kernel
sources that work well. I have another kernel I'm testing, although there
are problems alsa there. will report back  there is time!
