please report bugs for openSUSE against SUSE 10.0 and take a look at:  http://

Comment 2 Christian Zoz 2005-09-01 09:49:31 UTC

This did never work up to now (with single exceptions).

But perhaps it might work in future via:
  echo -n "1.0" > /sys/bus/ide/drivers/ide-cdrom/unbind
  unplug cdrom, do whatever, plug cdrom again
  echo -n "1.0" > /sys/bus/ide/drivers/ide-cdrom/bind
where "1.0" is the device id you see in 
  ls /sys/bus/ide/drivers/ide-cdrom
But that is just an idea. I don't know we have any other reasonable means to
achieve this.
Donald, you may fiddle around with that. If you find out sth, please let us know.

Jens, do you have any interesting information regarding this?
Seife, any practical experiences, ideas?

This will not be solved for 10.0. Its to late.
Stefan, this must become a feature request.

Comment 3 Jens Axboe 2005-09-01 10:17:49 UTC

Hot swapping support for pata/sata isn't implemented in the kernel, so it cannot
work yet. It requires more work.

Comment 5 Christian Zoz 2005-09-30 15:36:24 UTC

Will we get this some day? Is somebody working on that?

If hot swapping is just a nice dream, then please close this bug as WONTFIX.

This question is for Jens of course.

Comment 7 Jens Axboe 2005-10-18 11:26:56 UTC

It's being worked on, but nothing definite or merged yet.
