Problems with cd writer

Hi all - I have a burning problem on my workstation with ide-scsi:

The modules seem to load correct:

gentoo root # lsmod
Module Size Used by Not tainted
ide-scsi 8464 0
sg 27500 0 (autoclean)
sr_mod 17592 0 (autoclean) (unused)
ide-cd 29800 0 (autoclean)
cdrom 28928 0 (autoclean) [sr_mod ide-cd]

cdrecord sees the devices:

gentoo root # cdrecord --scanbus
Cdrecord 2.01a05 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
Linux sg driver version: 3.1.24
Using libscg version 'schily-0.7'
scsibus0:
0,0,0 0) 'RICOH ' 'CD-R/RW MP7063A ' '1.30' Removable CD-ROM
0,1,0 1) 'LITEON ' 'DVD-ROM LTD163 ' 'GH5E' Removable CD-ROM
0,2,0 2) *

I am able to mount a cdrom in the DVD device:

gentoo root # mount -t iso9660 /dev/sr1 /mnt/cdrom2
mount: block device /dev/sr1 is write-protected, mounting read-only
gentoo root # ls /mnt/cdrom2
Demos LinuxTag Talks autorun.inf index.html
KNOPPIX Makingof autorun.bat cdrom.ico
gentoo root # umount /mnt/cdrom2

When I try to mount a cdrom in the CDR Linux freezes =8-|

o This workstation with CDRW and DVD worked with SuSE and Debian
o I am abble to access CDWR as /dev/hdb
o I am able to write CD's with cdrecord dev=ATAPI
o Burning on my IBM thinkpad running gentoo works perfekt...
o hdb and hdd are treated the same in modules.conf, menu.lst, /etc/modules.d/cdr

Any Ideas?

how are you trying to mount a cd in the burner?
with /dev/sr0 ?

I'm confused. Are you trying to mount a CD...To then burn to it? You don't need to mount it in that case. cdrecord or whatevcer will take care of everything.

I am trying to mount the cdrw with /dev/sr0, thats right.

@puggy: I can't access the CDRW. When I tried to burn, Linux freezes, so I simply tried to mount a CD with the same result. No entries in the logfiles, dead keyboard, reset :-(

You can mount a normal CD-ROM in the drive no problem?

I *cannot* access the CDRW at all - no reading (of course a written CD) and no writing in the /dev/sr0 device. The DVD device in /dev/sr1 works.

I am using the latest sources:
gentoo root # uname -r
2.4.20-gentoo-r5
