Those errors may be appearing if/because you're trying - directly or indirectly, via fstab or elsewhere - to explictly mount an audio cd: whereas of course there's no filesystem on an audio cd for mount to work with - it's an old chestnut. I've just now double-checked and verified this on an old-ish machine (p4 2.4ghz, ide) running slackware-13.0 (uses 2.6.29.x kernel, and 'hda/hdb/hdc/...' device naming), and using Xfce as Desktop Environment: put an audio CD into cd/dvd drive (here, it's /dev/hdc aka /dev/cdrom), do 'mount /dev/cdrom /mnt/tmp' (or similar) on command-line, and ... hey presto, almost exactly the same set of error messages as you list, show up here in /var/log/syslog . As for how to _stop_ the errors on your setup: I don't really know in enough detail, how to tell HAL/whatever to handle/detect audio cd -vs- data cd, or even if they need/want to; but, hopefully the info that you typically can't mount audio cd in the same way as data cd, will be of help. akhiezer -- -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
