Hi everybody,
I'm using Debian Sqeeze 6.0, kernel 2.6.32, udev version 164.
With kernel provided from debian my dvdrw is under scsi subsystem and
udevadm monitor recognize optical disk change with a lot of info output
suitable to write rules.
I've recompilated the kernel and things has changed, now my dvdrw is under
ide/atapi subsystem and the device name is hdc now.
I'd like to write a rule that remove udf and crc_itu_t modules as soon as
optical disk is left off from dvdrw drive. Example:
SUBSYSTEM=="block", KERNEL=="hdc", ACTION=="change", RUN+="/sbin/rmmod udf
crc_itu_t"
I look at http://reactivated.net/writing_udev_rules.html but doesn't help
for ide devices ACTION=="change".
Could anybody help me to write such a rule?
Modern userspace and kernel facilities like media change polling do
not support all the old and deprecated IDE drivers. The IDE drivers
are just not capable to do what you are looking for. Udev does not
support IDE drivers at all, only libata.
You might just want to disable the IDE drivers in the kernel config
and use the libata ones. Ideally the kernel would just delete the IDE
stuff.

Thank you very much Kay,
does libata work as a kernel module only or can be statically included
into the kernel? My lsmod output is:
# lsmod
Module Size Used by
vboxpci 11426 0
vboxnetadp 17099 0
vboxnetflt 13500 0
vboxdrv 1754521 3 vboxpci,vboxnetadp,vboxnetflt
that are Virtual Box modules. I've included into the kernel usb, sound,
network, sata, ide, and other devices support. Modules are ppp, usb
specific drivers, lp ... and others but not libata. Maybe should I
looking for a more recent, backported to sqeeze linux kernel?
bye,
