Is the CD unreadable, or is it just that the printf's are annoying? If it's really unreadable, the problem must be the ``name '' - type ...'' thingie, the RR[5]'s are benign. From a quick glance over the code, i've got no idea. If it's simply annoying, kill the printf's out of isofs_rrip.c, and recompile your kernel. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
