CD oddities with VIA PATA

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 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.
