I've got an HP 6930p with x86-"stable" installed. I can play video DVDs, read CD and DVD data disc, but audio CDs give me numerous repetitions of this sort of thing: Jan 30 18:57:48 aus8617 kernel: end_request: I/O error, dev sr0, sector 96 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] Result: hostbyte=0x00 driverbyte=0x08 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] Sense Key : 0x5 [current] Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] ASC=0x64 ASCQ=0x0 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] CDB: cdb[0]=0x28: 28 00 00 00 00 1a 00 00 02 00 Jan 30 18:57:48 aus8617 kernel: end_request: I/O error, dev sr0, sector 104 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] Result: hostbyte=0x00 driverbyte=0x08 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] Sense Key : 0x5 [current] Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] ASC=0x64 ASCQ=0x0 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] CDB: cdb[0]=0x28: 28 00 00 00 00 38 00 00 01 00 Jan 30 18:57:48 aus8617 kernel: end_request: I/O error, dev sr0, sector 224 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] Result: hostbyte=0x00 driverbyte=0x08 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] Sense Key : 0x5 [current] Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] ASC=0x64 ASCQ=0x0 Jan 30 18:57:48 aus8617 kernel: sr 1:0:0:0: [sr0] CDB: cdb[0]=0x28: 28 00 00 00 00 39 00 00 01 00 I've done some Googling, and found a few recent similar errors in Ubuntu, but no real solutions. As such, I believe it's a kernel problem, but not sure if I should file against the Gentoo kernel, or the general Linux kernel. I figured I'd start here.

If you start with an older kernel, does it then work again? Also, please attach your kernel .config. Also, find a simple program to play an audio CD, and provide the steps to reproduce the problem using that program. Did you try different audio CDs? Does it play any sound at all? Does the drive make the usual reading noises?

I haven't tried with an older kernel; I've only got 2.6.34-r6 & 2.6.34-r12 on here; is that old enough, or do you want me to try older? I've tried down to cdplay at a command prompt, no X running, and it gives the following: jmoe@aus8617 ~ $ cdplay --device=/dev/cdrom -v -c Playing from CD-Track: 1 Playing cd-track: 1 [02:15] Playing cd-track: 2 [07:14] Playing cd-track: 3 [04:16] Playing cd-track: 4 [08:52] Playing cd-track: 5 [06:10] Playing cd-track: 6 [02:48] Playing cd-track: 7 [05:21] Playing cd-track: 8 [04:53] Playing cd-track: 9 [02:25] It doesn't actually play the tracks, it skips from one track to the next about every second. So it's reading the CD, it just can't play the audio for some reason. And I've tried a few different CDs, and made sure they were straight audio CDs (not mixed data/audio CDs), and still the same problem. Also, I forgot to mention in the original description, that I *can* use cdparanoia and cdda2wav to rip the music off the CDs, but I can't play the audio directly.

Assuming that a kernel update caused this issue, it would be nice to find out which kernel it does work with. It should be rather easy to just whip out some aging Live CD on a bootable USB drive to test just this with. Also, emerge lsscsi and print the output of `lsscsi -v' so we know what model the drive is.

Output of lsscsi -v attached. The assumption that it was caused by a kernel upgrade is false. This is a new(-ish) build that I hadn't tested CD audio on until I wanted to rip some more CDs from my collection to my hard drive. When I tried that (on the current kernel), I couldn't get anything to recognise it. However, I've got a previous kernel build I'll boot to and see if it makes any difference. And I'll dig out an older Gentoo build CD and test with that, and get back to you on whether it works.
Well, I just tried it with my 2.6.34-r6 kernel, and that gave the same results when I tried to use cdplay. I'll have to try and find an old LiveCD of some sort and see if I get different results.
It could be useful to know which similar problems you found in Ubuntu.
Can you possibly try another distro's live cd, maybe Knoppix? This might not be a kernel issue at all.
