that is: i could burn 1 dvd, which works fine, then the next i burn fails, with io error, then the third i burns works.. in short, every second works.. unless i reboot after each, then no one fails.. its a insanely strange problem. :) but atleast im able to get abit free hd space now :) > > > > > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to [EMAIL PROTECTED] > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
