Hello,
I need some additional info from you. Please, run eject (without a patch) in a
verbose mode "$ eject -v -X" and create an attachment. Also create an attachment
with an output of "$ cat /proc/sys/dev/cdrom/info".

Thanks

This is a patch fixing this bug

This patch avoids giving up too early the speed detection: in case of error,
just try with the next speed.

Comment 6 Zdenek Prikryl 2008-02-15 13:33:27 UTC

Patch seems fine. But still, I would like to have some additional information. 
Because this is first case of this kind of problems, a bug could be in a 
kernel module of cdrom. So, what cdrom do you have? Please, attach an output 
of "$ lsmod" as attachment too.

Thanks

The attachment of executing command "lsmod"

I execute command in the machine "Acer Altos G530(SATA)"

Comment 8 Zdenek Prikryl 2008-02-28 13:30:20 UTC

Please try to build eject-2.1.5-5.el5.src.rpm which I'll create as an
attachment. This version tries to list speeds of a cdrom in different way.

Please, let me know, if this version works correct.

This is a patch fixing this bug in the source of "eject-2.1.5-5.el5.src.rpm"

This version does not work correct, the bug is still existent. So I make a
another patch to fix this bug in the source of "eject-2.1.5-5.el5.src.rpm".

Comment 11 Zdenek Prikryl 2008-03-06 10:47:54 UTC

Hello, one more test. Because eject fails to set some low CDROM speed, we try
another tool.

So run this as a root:
$ for s in `seq 0 1 52`; do hdparm -E $s /dev/hda; done

Will every set of speed run without any error?

The attachment of executing command "for s in `seq 0 1 52`; do hdparm -E $s /dev/hda; done"

BTW, The function ioctl(fd, CDROM_SELECT_SPEED, speed) when the speed is 1, 2
or 3 will return -1.

Comment 13 Zdenek Prikryl 2008-03-11 12:13:21 UTC

Hmm, it's really strange. As I mentioned before, it may be a kernel stuff. So
I'm reassigning this to kernel and will wait for their statement.

Comment 14 Anton Arapov 2008-07-04 07:08:09 UTC

  It's obviously normal return of the ioctl(). Nothing really strange happened,
it's device dependent.
  No doubts that eject tool have to deal with other then successful returns from
ioctl(), it will not break the logic of the tool and does not change the
behavior. Proposed there patches for eject is what I'd like to see in eject.

Alternatively, you can try to update the firmware in cd/dvd drive. Or at least
to look for it,... it might be known issue.

go ahead, Zdenek!

Comment 15 RHEL Program Management 2009-03-26 16:46:51 UTC

This request was evaluated by Red Hat Product Management for
inclusion, but this component is not scheduled to be updated in
the current Red Hat Enterprise Linux release. If you would like
this request to be reviewed for the next minor release, ask your
support representative to set the next rhel-x.y flag to "?".

Comment 20 Kamil Dudka 2010-03-26 16:40:04 UTC

The proposed solution does not solve the problem, which seems to be caused by the device (or its firmware).  As there is nothing we can improve in eject itself wrt. the issue, I am closing the bug as CANTFIX.  Feel free to reopen if you are aware of another solution.  Thanks in advance!
