The kernelcrash is reproducable by taking the livecd, uncheck all repo except yours run apt-get update && apt-get upgrade Good job anyway... tnx.. OT: btw.. pls let me know if I may ask you a little scriptquestion, on topic of ironkey, but offtopic for this bug. Best Regards, Bankey 2010/10/7 Martin Pitt
