| |
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.
