Kernel Bug Tracker – Bug 13921
No CD-ROM ATAPI driver on kernels higher than 2.6.24.x
Last modified: 2010-01-25 15:43:48 UTC
CDROM ATAPI. MODEL : DVD A DH20A4P.
Any newer GNU/Linux distribution (like Fedore 11, new Mandriva, Ubuntu 8.10,9.04,9.10) don't detecting cdrom drive. I can't install any distribution, because installer can't see my cd-rom drive. Working perfect on 2.6.24-24. Problem is on kernels line higher than 2.6.24.x.
Reassigned to IDE.
Can you send me the bootup messages of the working and failing kernels?
Won't be an IDE issue as Fedora 11 (and likely others in that list) uses libata.
Yes, bootup messages would be useful (or at least some kind of hardware description).

Bootup message ? Hmm... dmesg log from working Ubuntu 8.04 and dmesg from other distro ? Hmmm... that's be hard, because i can't install any new disto with kernel high than 2.6.24.x. Only way to get dmesg message is to upgrade my Ubuntu 8.04 to 8.10 and then get dmesg.log.
I attach dmesg from my Ubuntu 8.04.

Well, not too much exciting there, it's using the pata_atiixp driver, except that it's limiting the transfer speed to ATA/33 because of a 40-wire cable detection.
Can you boot up with a newer distro install disc and get to a command shell somehow to get at the dmesg output?
I'm afraid i can't, because installers stop responding or they don't see cd-drive and can't install without it. Many installers don't have shell option. I have this problem on every distro with kernel higher than 2.6.24.x (it's only one problem, because i've submitted two other bugs). I can't use any Ubuntu higher than 8.10 (because i have BusyBox), but i can upgrade 8.04 to newer version. On 8.10 - i don't have cd-rom drive and card reader (but i've submitted this bug). I can upgrade and get dmesg from Ubuntu 8.10.
p.s : sorry for terrible english - it's not my native language.
Ubuntu uses libata (Debian still uses IDE BTW).
pata_atiixp have blatant bugs which were never present in atiixp (I happen to be co-author of the original driver).. I'll send a fix later today..
The fix was posted but unfortunatly I don't think this will help in this case as it looks more like generic device detection problem.
Krystian, if you can run Ubuntu 8.10 at all and retrieve dmesg from it, that would be useful to help determine why the drive is not detected..
Ok - now i have Ubuntu 8.10 (upgrade from 8.04) with 2.6.27-7-generic kernel. I don't have cd-rom drive and card reader (but i've submitted this bug too).
p.s : i've attach dmesg.log from first boot on this version of Ubuntu.

dmesg.log from Ubuntu 8.10 with 2.6.27-7-generic kernel
So on previous kernels we got:
[ 27.697747] ata5.01: ATAPI: ATAPI DVD A DH20A4P, 9P59, max UDMA/66
whereas now we have:
[ 5.544062] ata5.01: NODEV after polling detection
Hmm, why is the device being detected as device 1 instead of device 0? Is it the only device on the IDE channel and jumpered as slave? That's not really a good configuration.
There was a rather recent change to NODEV_HINT handling for bko#7241. Doesn't seem that could affect this one tho. Krystian, can you apply kernel patches and build kernels?
Patch not working :-( I've compiled 184.108.40.206 with patch. Still no sign of cd-rom drive. I'm switching back to Ubuntu 8.04 and 2.6.24-24 kernel. Attaching dmesg.log from 220.127.116.11.

dmesg.log from 8.10 on 18.104.22.168 kernel.
Heh heh, which patch? :-) I was curious whether you could apply a patch and build and test the patched kernel. Looks like you can. I'll post a debug patch soon. Thanks.

Can you please apply the attached patch and post the resulting boot log? Thanks.
Still no CD-ROM drive. Tested kernel - 22.214.171.124. Dmesg.log attached.

dmesg.log with Tejun Heo patch (126.96.36.199).
Created attachment 22683 [details]
Thanks for testing. The patch wasn't supposed to fix anything. It just shows what's going on. It hit NODEV1 which is the oldest NODEV condition - device status is zero - no DRQ on BSY deassertion. I'm not sure what makes 2.6.24 different tho. It's just so long ago and there have been a lot of changes. One possible candidate is switch to IRQ-driven PIO. The device is required to set DRQ before deasserting BSY but ISTR devices which have a short window between BSY deasserting and DRQ assertion. If IDENTIFY is done by polling, this problem can be masked as the status polling interval is quite long. If this is the case, we probably need a mechanism to delay check status if !BSY && !DRQ.
Does the attached patch make any difference?
Nothing changed :-( Dmesg attached.
p.s : On 188.8.131.52 my card reader working again :-) This reader stop working on kernels higher than 2.6.24.x. I've submitted this bug... and working again :-) Thanks :-)

dmesg from pata_atiixp-pio-polling.patch
Hmmm... strange. The device still works with older kernel, right? If so, are you interested in shipping the drive to me? I'll pay for the replacement unit and shipping.
I'm really sorry, but it's impossible :-( And i'm from Poland, so... long way :-) I'm reading technical information about my PC, and my cdrom drive is : "DVD+/- RW LiteON DH-20A3P". Maybe this information helps you. And yes - CD works on lower kernel (at this moment 2.6.24-24). This cdrom drive is popular, because most of pc have this drive, so i'm sure you find this device without any problems.
Still nothing on 2.6.31-rc7 :-(
I know this bug is in changelog for previous rc version, but i can't boot system on 2.6.31-rc6. So i can't test it :-(
I can't run system on 2.6.31-rc6,, because system stop responding on:
"Start kernel log daemon"
Or something like that.
At least my MMC/SD card reader working again :-)

dmesg from 2.6.31-rc7
I still don't have much idea what went wrong there, so couldn't do anything. :-( And, unfortunately, liteon presence is somewhat weak here in Korea and I couldn't find the unit. It used to be on market but none are carrying it anymore.
Would you be interested in bisecting the problem?
Now working on 2.6.30-1 - some time ago not. Ive compiled 2.6.31-rc7, but still cd-rom is not detected. I don't know how why, but now cd-rom is detected on 2.6.30-1. I can't send you my cd-rom drive, so tell me what you need. It's really important for me, because installers of actual distros... installers of this distros don't detect my drive, so i can't install them. I have ploblem with Busybox too, but i've submitted this bug some time ago.
We currently don't know what went wrong but it went wrong somewhere between 2.6.30-1 and 2.6.31-rc7, right? By bisecting, the commit which broke the detection can be discovered, hopefully. The following page explains how it works.
When i'm using Debian Testing some times ago (when 2.6.26 was on top), and kernel don't detecting cd-rom and my card reader - even on compiled 2.6.30. I was used compiled 184.108.40.206. Later i was switched to Ubuntu 8.04. Yesterday i've installed Debian Testing. Default kernel in this version at this moment is 2.6.30-1. Suprise - cd-rom drive and card reader works fine. I've put 2.6.30-1 config from /boot and compiled 2.6.31-rc7. Card reader still working, but again - i don't have cd-rom drive. So yes - regression is somewhere between 2.6.30-1 and 2.6.31-rc7.
p.s : What should i do with this bisecting ?
The goal of bisection is revealing (hopefully) exactly which commit caused the regression. As kernel is always updated in discrete logical steps, locating the offending commit usually directly points to the cause of the regression. Can you do it?
Yes - just tell me what should i do.
Ummm... the git-bisect man page is pretty descriptive about the bisection process. You start with a known good commit (in this case 2.6.30 vanilla) and a known bad commit (2.6.31-rc7) and then start binary search for the culprit. The following page might help too.
OK.. but where i can get this bisect...? I can't find bisect in debian repository :-/
Oh... it should be a part of git package(s). On my system, it's
# rpm -qf `which /usr/lib64/git/git-bisect`
# rpm -qa|grep ^git
"bash: git-bisect: command not found"
fatal: Not a git repository (or any of the parent directories): .git
This is reason why im asking :-)
The "-" dash commands were deprecated, so replace "git-bisect ..." with "git bisect ..."
Run "git help bisect" for additional information.
You will want to run the bisect inside the git repository and working tree.
1. git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-git
2. cd linux-git
3. git bisect start
4. git bisect bad v2.6.31-rc8 :
"fatal: Needed a single revision
Bad rev input: 2.6.31-rc7"
5. git bisect good 2.6.30:
"fatal: Needed a single revision
Bad rev input: 2.6.30"
This stuff is a nightmare to debug.
I've compiled 2.6.39-rc9 and i found this in dmesg log:
[ 0.830789] atiixp 0000:00:14.1: IDE controller (0x1002:0x438c rev 0x00)

Not 100% native mode? I think there must be some bug in the driver. Sorry about bisect, but this stuff is really hard to use - see my previous post.

dmesg from 2.6.31-rc9
The "not 100% native mode" thing is normal, but it looks like you're running with the old IDE drivers now.
As I mentioned before, you should check if your drive was jumpered as the slave device and the only device on the channel, if so you should fix that as it's not a good configuration.
CD-ROM drive working on 220.127.116.11, but not on 2.6.31-RCx.

Configuration is ok :-)

Dmesg.log from 18.104.22.168 (working cd-drive).
You're using IDE drivers now. pata_atiixp behaves the same?
Does libata.force=norst make any difference?
Nothing changed. I think there is some regression in driver. I have this same .config file to compile kernel. CD-ROM working fine on compiled 2.6.30-6, and on 2.6.31 (used this same .config file to compile) - device is not detected. I really don't know what to think - it's only cd-rom drive :-/
And we have 2.6.32-rc2 kernel, and CD-ROM drive not working... One year of regressions and still there is this damn regression. I have small business - 10 PC with this same CD-ROM drive model and motherboard, and this device (cd-rom) works only on two kernels - 2.6.24 (and lower) and 2.6.30-6. It's not funny - Linux must be professional kernel without that kind of regressions (it's only stupid cd-rom drive!). Maybe i must mark something, when i'm compiling kernel? It's not funny when you MUST use 2.6.30-6, when 2.6.32 have release candidate version. Why you can't use newest kernel? Because newest kernel can't detected very simple (and VERY IMPORTANT) device like cd-rom drive... Linux is not a toy and test fields for that kind of bug. Ech...

You didn't really answer the question - for whatever reason the device was/is being detected as being device 1 (slave) instead of device 0 (master). Either it's being incorrectly detected that way for some reason, or the device is really jumpered as slave without a master device, which isn't guaranteed to work.
Emm...i've change cd-rom drive from slave to master. Now it works :-D Device works on 2.6.32 and other distros. So...changing to master solved the problem.
But im thinking about it - if someone have two cd-rom drives, first on master, second on slave, only first drive on master will be detected. It's not fair... many poeple have two cd-rom drives, and only one on master will be used.
May i asking why my device was not detected on slave?
Anyway - many thanks to you all. And again - sorry for my english - im from poland.
If you had a device on master and on slave there would likely be no problem. The problem is having a device on slave only. This is what the ATA standards call a "Device 1 only configuration". The last version of the ATA standard (ATA-6) that referred to them said that "Host support of Device 1 only configurations is host specific", in other words, optional. Later versions of the standard deleted references to such configurations entirely.
Ideally the device would work with a slave and no master, but there are a number of complications in detecting the device in such a setup (and potentially unavoidable hardware bugs). Even some BIOSes won't detect a slave drive if there's no master.
Need a parameter for the module, like hdX=cdrom for old ide-driver...
At least problem is solved. CD must be set to master - all distros works now. Thanks for help and hint (change slave to master).
