Apparently it gets indigestion on the fact /dev/cdrom is a symlink to /dev/sr0 - "--device /dev/sr0" works fine.

Proposed patch

Problem is quite simple. Second realpath(3) argument is too short. It should be at least PATH_MAX bytes (which is currently 4096 B), not HAL_PATH_MAX (512 B). Patch fixes this issue and, I believe, is better than original approach with fixed-length array.

Comment 2 Bug Zapper 2010-03-15 13:52:56 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 13 development cycle.
Changing version to '13'.

More information and reason for this action is here:

Comment 3 Niels de Vos 2010-05-31 13:23:45 UTC
Confirming the same bug with Fedora 13 and hal-0.5.14-3.fc13.x86_64.

powertop advised me to execute that command, I expect lots of people will hit the same bug :-/

The workaround as mentioned in the opening comment works for me too:

# hal-disable-polling --device $(readlink -f /dev/cdrom)

Comment 6 Jan Vcelak 2010-07-13 16:49:28 UTC
The same problem on F13 and Rawhide.

Please, can you fix this bug ASAP? This makes profile switching in tuned to crash.

Comment 8 Matthias Runge 2010-09-10 18:48:56 UTC
I can confirm this problem for recent F14
naming the device by its correct name (not the symlink) hal-disable-polling seems to work fine.

Comment 9 MartinG 2010-09-29 19:40:58 UTC
Another me too:
# hal-disable-polling --enable-polling --device /dev/scd0
*** buffer overflow detected ***: hal-disable-polling terminated
Aborted (core dumped)

# hal-disable-polling --enable-polling --device $(readlink -f /dev/scd0)
Polling for drive /dev/sr0 have been enabled. The fdi file deleted was


Fedora Rawhide.

Comment 11 Bug Zapper 2011-06-02 16:54:25 UTC
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '13'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 

Comment 12 Niels de Vos 2011-06-05 11:32:30 UTC
Fedora 16 will very likely not contain hal anymore and therefore will obsolete this bug:

Comment 13 Pavel Alexeev 2011-06-06 09:11:42 UTC
*** Bug 577526 has been marked as a duplicate of this bug. ***

Comment 14 Bug Zapper 2011-06-27 14:47:28 UTC
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
