Experimenting with the CD dump program cdda2wav I find that if I carelessly misstep or omit a command line device parameter, the process hangs and can not be killed with SIGKILL ,i.e.. -9, even by the super user. I am making a wild guess that this condition is caused by some kernel io process, as yet unidentified: it does time-out and the calling process, cdda2wav, dies. I make this assumption because of the large amount of cpu usage used by system at this time as shown by top. So far I have only observed this with a music cd in the drive, but I have no reason to believe that the same problem would not occur with a data, iso9660, cd. It may be possible that a misconfiguration could cause the same symptoms. kernel 2.4.4, Pentium 133 Ralph Gesler - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
