LinuxQuestions.org - 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

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

# cat /etc/fstab

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
