I have debian 2.6.8-2-k7 latest kernel-image.
2.6.10 is not ready for k7.

Another info I grabbed from /var/log/messages tells:

kernel: hdc: media error (bad sector): status=0x51 { DriveReady
SeekComplete Error }
kernel: hdc: media error (bad sector): error=0x30
kernel: end_request: I/O error, dev hdc, sector 64
kernel: isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16

Is it normal to get a DriveReady SeekComplete Error with a dvd ?

Sure, I have iso9660 support.
