Red Hat Bugzilla – Bug 163746
hal prevents me from ejecting CD-ROMs
Last modified: 2012-06-20 12:18:25 EDT
Sometimes I cannot eject CDs from my drive. This doesn't happen all the time,
but it's often enough to be really annoying. Pushing the button on the drive
does nothing. So I tried issuing the "eject" command. The command hangs and
never completes. "ps aus |grep eject" shows that the process is in
[root@verve boot]# ps aux |grep eject
bfox 3070 0.0 0.0 4612 672 pts/7 D+ 15:15 0:00 eject
I ran "lsof | grep hdc" and I see that hald is keeping the device open:
[root@verve boot]# lsof | grep hdc
hald 2923 root 3r BLK 22,0 749 /dev/hdc
hald 2923 root 13r BLK 22,0 749 /dev/hdc
I then ran "service haldaemon stop" which appears to stop hald, but the process
never exits. "ps aux |grep hald" says:
[root@verve boot]# ps aux |grep hald
root 2923 0.0 0.6 8900 6172 ? Ds Jul18 0:42 hald
A reboot seems to be the only way to get my CD out. Why does hal go into an
uninterruptible sleep sometimes?
We've observed the same behavior (hal-0.4.2-6-EL4).
In some cases what seems to trigger this condition is when playing
certain audio CDs, and in particular, if the audio CD is an 'enhanced'
CD with data/application that can be run on a regular Windows O/S,
it seems to leave hal in the state where eject will no longer work.
In some cases a stop/start of haldaemon will clear the condition.
root will always be able to eject the CD (while a non-privileged
user cannot); else a reboot is the only recourse to restore eject
Agreed, quite annoying.
