Description of problem:
I am unable to copy files from VCDs to the computer. And I am also unable to play such files from VCDs. 

Fedora Core 6 is the first version of Fedora I am using. So I don't know if it appears in previous versions. I think its a kernel problem coz I can reproduce the error in other distros such as openSUSE 10.2 and Slackware 11. The problem appears to be in kernels 2.6.16 and above. I have tried kernels at random from the 2.6.17 series, the problem persists. I tried a kernel at random from the 2.6.16 series (2.6.16.23) and can't reproduce the problem there. 

There's two parts to this problem.

First part is that if you insert a VCD into the drive, dmesg immediately spits output like this:

hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }

Its not even possible to mount the VCD or copy files off it! 

I have tried this with many different VCDs. All of them working normally in my VCD player or Windows. And I've tried these different VCDs on both Fedora Core 6 and other distros (mentioned above). When I dabbled with Linux a while ago (Fedora Core 4, Ubuntu etc) I know this was no problem ... it was possible to mount VCDs and copy files off them. 

I reported this to the LMKL (and also filed a bug at bugzilla.kernel.org). They tell me its a HAL issue and that nothing was changed in the kernel with respect to CD access. So I fooled around a bit more. Disabled HAL and sure enough the problem is gone. And I finally tracked the problem down to the fact that HAL has a polling module for the CDs and that is what causes all these errors to appear as soon as the CD is inserted. Modified HAL to disable CD polling, and sure enough I can mount VCDs without any hassles.

Now for part two.

After mounting I tried to copy the files from VCD to hard disk. (I also tried playing the file using Totem, VLC etc). It fails! On the command prompt I get an Input/ Output error, and dmesg starts spitting out errors like the above again. 

Just to confirm that its no HAL etc problem at all, I booted into single user mode and tried. And I can reproduce the errors there too. 

On Slackware 11 (where I get the same errors) I downgraded the kernel to 2.6.16.23 and that solves the problem! All this leads me to think its a kernel issue. 

As an aside, Xine is able to play the VCDs fine. It doesn't mount them, but access the tracks directly -- so it isn't affected. 

Version-Release number of selected component (if applicable):
kernel-2.6.18

How reproducible:
Always


Steps to Reproduce:
If HAL is active: 
1. Insert VCD.
2. Check dmesg. 

If HAL is inactive (eg. single user mode):
1. Insert VCD.
2. Mount VCD.
3. Copy files off VCD (or try to play one of them).
