Further report in case it is helpful for debugging it: Because I am a bit in hurry (now is 23:55, better finish today's backup before 00:00) I tried to issue command to mkisofs replacing '-M /dev/hdd' with '-M /tmp/first.iso' where first.iso is the iso image for the CDR I burnt first time. By doing so I can separate the mkisofs failure with possible DVD-RW driver problem (because driver is not used when doing this mkisofs). The behavior: mkisofs starts to run, and hang pretty soon there, taking up NO CPU RESOURCE. It simply hang there. Ctrl+C and TERM signal is ignored, KILL signal cause it to quit.
