CDWriter fails to work after running upgrade


Hi all folks,

Gentoo 1.4
Kernel 2.4.20

My CDWriter fails to work after running 'emerge -u world'

Followings are my tests;

1)
# cdrecord --scanbus (or -scanbus)
......
cdrecord:No such file or directory. Cannot open 'dev/Pg*'. Cannot open SCSI driver
......

# which cdrecod
/usr/bin/cdrecord

# cat /boot/grub/grub.conf
...
kernel (hd0,0)/boot/kernel-2.4.20-gentoo-r7 root=/dev/hde3 hdd=ide-scsi
initrid (hd0,0)/boot/initrid-2.4.20-gentoo-r7


2)
$ cdrecord --scanbus dev=ATAPI
Cdrecord-Clone 2.01a25 (i586-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling
scsidev: 'ATAPI'
devname: 'ATAPI'
scsibus: -2 target: -2 lun: -2
Warning: Using ATA Packet interface.
Warning: The related libscg interface code is in pre alpha.
Warning: There may be fatal problems.
Using libscg version 'schily-0.8'.

The CD-ROM is there but CD Writer gets lost !


# cdrecord dev=ATAPI:0,0,0 speed=4 blank=all -v -eject
....
TOC Type: 1=CDROM
......
......
cdrecord: No disk /Wrong disk

# cat /etc/fstab

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hde1 /boot ext2 noauto,noatime 1 1
/dev/hde3 / reiserfs noatime 0 0
/dev/hde2 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
/dev/fd0 /mnt/floppy auto noauto 0 0

# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0

# Adding the following line to /etc/fstab should take care of this:

none /dev/shm tmpfs defaults 0 0

CDWriter is not there. Kindly advise how to find which device belongs to CDWriter.


3)
Before 'emerge -u world' the CDWriter worked without problem. I have not done anything to compile scsi emulation as a kernel module. If it was done automatically during 'emerge -u world' I was not aware Because it took 6 x 24hrs to complete on this slow machine.

Kindly advise how to fix it.

TIA

B.R.

hmm.. I wonder if that line tells something...

do you use unstable packages with emerge, so that your update might have installed very new, perhaps not correctly working, packages? if so, then it might be the reason...solution would be to install older (newest _stable_) version of libscg.
