    SubjectCD oddities with VIA PATA
     I'm testing 2.6.19 on this box, and I thought I might as well try
    out the Parallel ATA driver for the CD/DVD writer (VIA) since the
    disk is already handled by libata.

    So far, I've found two oddities -

    (i.) cdparanoia (9.8) works for root, but for a user it complains
    that the ioctl isn't cooked and refuses to run. For test purposes,
    it runs ok for a user as suid root, but I imagine that increases
    the likelihood of unspeakable things happening. (Fortunately, I
    don't have a dachshund)

    (ii.) As a user, I burned a small (28MB) CD using dvdrecord from
    dvdrtools-0.3.1, and on a different box I can mount it (using
    ide-cd) and it seems fine. On this box I can't mount it -

    ken@ac30 ~ $mount /media/cdrom/
    mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
    missing codepage or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so

    The syslog shows

    Dec 1 21:17:41 ac30 kernel: attempt to access beyond end of device
    Dec 1 21:17:41 ac30 kernel: sr0: rw=0, want=68, limit=4
    Dec 1 21:17:41 ac30 kernel: isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

    The iso is the gparted-livecd-0.3.1-1.iso.

    The problem might be specific to small CDs, I can mount others (41M
    of data and more) without difficulty and all of the likely NLS options
    are selected as =y in my config.

    das eine Mal als Tragödie, das andere Mal als Farce
