Hi all
I tested 2.5.70 with scsi-ioctl-2 patch
It works fine until It has to read the last sectors. I get the following messages from readcd, using different CD-Rs
agapito:~# readcd dev=/dev/hdc f=/dev/null Read speed: 8450 kB/s (CD 48x, DVD 6x). Write speed: 7056 kB/s (CD 40x, DVD 5x).

dmesg shows several hdc: confused, missing data and then (sometimes) cdrom_newpc_intr: 2048 residual after xfer for each run of readcd
readcd version comes from
ulisses@agapito:~$ dpkg -l | grep cdrecord ii cdrecord 2.0+a14-1 A command line CD writing tool
the CDR/W recorder is not the best thing on this world... agapito:~# cdrecord dev=/dev/hdc -checkdrive Cdrecord 2.01a14 (i686-pc-linux-gnu) Copyright (C) 1995-2003 Jörg Schilling scsidev: '/dev/hdc' devname: '/dev/hdc' scsibus: -2 target: -2 lun: -2 Warning: Open by 'devname' is unintentional and not supported.

Can I do anything else?
