I am pleased to report that your kernel-2.6.30 patch
(0001-ide-cd-prevent-null-pointer-deref-via-cdrom_newpc_in.patch)
fixed the crash problem when accessing my /dev/hdd dvd-rom drive. I was able to
mount a dvd-rw disc & here is the proof:
[root@localhost stan]# mount -t iso9660 /dev/hdd /mnt/misc
mount: block device /dev/hdd is write-protected, mounting read-only
[root@localhost stan]# df -T
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda2 ext4 60G 4.3G 52G 8% /
/dev/sda1 ext3 54M 16M 36M 31% /boot
/dev/sda6 ext4 60G 3.1G 53G 6% /usr
/dev/hdd iso9660 400K 400K 0 100% /mnt/misc
[root@localhost stan]# mount -t iso9660 /dev/hdc /mnt/cddrive
[root@localhost stan]# df -T
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda2 ext4 60G 4.3G 52G 8% /
/dev/sda1 ext3 54M 16M 36M 31% /boot
/dev/sda6 ext4 60G 3.1G 53G 6% /usr

/dev/hdc iso9660 350K 350K 0 100% /mnt/cddrive
I edited the kernel-2.6.30 "ide-cd.c" file as instructed to apply the patch &
then ran the following
commands to re-compile my kernel:
make mrproper
cp .config-save .config
make oldconfig
make
make modules_install
My "new" /lib/modules/2.6.30/drivers/ide/ide-cd_mod.ko showed file size =
35133 bytes.
The "orig" /lib/modules/2.6.30/drivers/ide/ide-cd_mod.ko showed file size =
35125 bytes.
I also inserted a commercial video movie disc & a cd-rw disc in problem drive
/dev/hdd.
Everything seems too work fine. Thank you.
