full 2.6.25-rc5 dmesg

Thanks, the drive survives the probe (is identified correctly) but fails when there is a first attempt to use it with ide-cd.

Could you also send a dmesg from 2.6.23 (so we can compare these two)?

| Steps to reproduce:
| plug a plextor DVDR PX-740A as primary ide master.
| boot a kernel >= 2.6.24-rc1
|
| NB: if the plextor is on primary ide slave, there's no error.
| (the jumpers are ok).

Please confirm that I get this correctly - if the drive is plugged as master and configured by _jumpers_ as master it also fails?

[ Also: is the drive connected to the "other" cable end (_not_ in the middle)
  when used as master? ]

PS I'm cc:ed on all IDE bugs anyway so I've removed myself from cc:

| [ Also: is the drive connected to the "other" cable end (_not_ in the middle)
|   when used as master? ]

One more thing - please also verify that the cable is plugged correctly (not in the reverse order) - the connector farer from the middle one (blue one) should go to the controller.

[ Sorry for asking so many stupid questions but I would really like to exclude
  hardware configuration issue first. ]

yep!

doesn't work:
IDE drive configured by jumper as master AND connected to the end of the cable.

does work:
IDE drive configured by jumper as slave AND connected to the middle of the cable.

By the way, the presence of another drive on the cable doesn't seem to change anything.

[I didn't try:
IDE drive configured by jumper as master AND connected to the middle of the cable.
IDE drive configured by jumper as slave AND connected to the end of the cable.
but I can try if you want]

And the calbe I use is a 80 connector.

yes, it is.

It's all right, everything should be double-checked.

full 2.6.23 dmesg

Thanks.

I've rechecked with the known ATAPI errata but so far I don't see a reason for drive getting stuck - I wonder whether it could be controller related.

Could you try using ide_pci_generic driver instead of amd74xx (you need to disable CONFIG_BLK_DEV_AMD74XX, enable CONFIG_BLK_DEV_GENERIC and boot kernel with "ide_pci_generic.all_generic_ide" option) and see if it helps?

Also booting with "hdb=noprobe" should workaround the problem (please try it).

This problem is widespread! I am experiencing it - like other users of
the Knoppix 5.3 live cd that came with a recent issue of the c't
magazine - here on a Nvidia MCP55 and a BenQ DW1655 which is master to
a Plextor PX-708A. Booting off the BenQ fails whereas booting off the
Plextor (slave) works.

Ciao,
  Dani

MCP-55 controller again, hmm...

- What error messages are you seeing?

- If you boot from slave drive does the master drive work?

when I disable CONFIG_BLK_DEV_AMD74XX and enable CONFIG_BLK_DEV_GENERIC, the kernel is booting without any error (whenever I add ide_pci_generic.all_generic_ide or hdb=noprobe).

I have the same bug :
https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/181561
and
http://bugzilla.kernel.org/show_bug.cgi?id=9837

I don't think that this is a controller problem. I have 2 different PC (nvidia and intel controller). And the bug follow is where i put my Plextor PX-740A (setting as master, and alone on ide).
Setting it as Slave resolve temporarly the problem.

*** Bug 9837 has been marked as a duplicate of this bug. ***

Richard, please send 'lspci -vvvxxx' outputs for:

- kernel using CONFIG_BLK_DEV_AMD74XX
- kernel using CONFIG_BLK_DEV_GENERIC + "ide_pci_generic.all_generic_ide"
  (+ dmesg output for this one)

and also:

- "bad" kernel using amd74xx
  (one with commit b140b99c413ce410197cfcd4014e757cd745226a)
- "good" kernel using amd74xx
  (one without commit b140b99c413ce410197cfcd4014e757cd745226a)

I'll see if there are any differences in the way controller is programmed visible in PCI configuration.

Patrice, please send dmesg output for the system with the Intel controller
(for the "bad" kernel).

Thanks.

downstream bug report: https://bugs.gentoo.org/show_bug.cgi?id=213615

Additional info sought at http://www.jmicron.com/Support_FAQ.html

Reason: Bug [probably] reproduced on ASUS Maximums Extreme SE motherboard latest BIOS, with dual DVDs connected to JMicron controller on motherboard, and, a separate 3ware 9620 RAID controller for HDs. Bug reproduced on Etch, Sabayon, Knoppix 5.1.1. The HW setup works fine for another OS.

Bug exhibits itself as follows: A bit down the installation, the CD-ROM cannot be found, despite ok booting from the device first. 
Booting DVD: LiteOn DH-16D2S (IDE)
Second DVD: Samsung SMSHS203 (SATA) (? May be a 202 which is IDE)

Though the use of all_ide_generic may work (not yet tried), it seems there are some performance side effects:

"Q6: What are the differences between Legacy mode (IDE) and AHCI mode? 
Ans: Legacy mode support s OS through legacy IDE driver. Most SATA functions are not supported in Legacy mode, like SATA II 3G, NCQ, HotPlug and etc. JMicron Technology Corp. delivers the worldwide first AHCI compliant eSATA controller and now most of the Operating Systems are "Native Support", which enables SATA II 3G, NCQ, and Hotplug on JMB36X SATA / eSATA controllers. 
 "

If I read correctly, I will disable SATA II speed enhancements (and then also on the nice RAID-controller?) if I use all_ide_generic or ide_pci_generic.all_generic_ide. That will be a problem.

Found workarounds so far:
Switch Slave/Master
Use "ide_pci_generic.all_generic_ide"
Remove CD and insert a USB-drive early in process
hdb=noprobe
Use network install
Let the distribution retry the mounting multiple times, "it then resolves by itself"

Not tried them yet, but thought summary might aid them wiser than me. Appologies if description not good enough. First time writer here.

For some reason the BIOS (if ide_pci_generic is used timings are not
programmed and the default values are used) sets higher address setup
time than amd74xx driver.

The timing used by amd74xxx is correct w.r.t. drive requirements,
ATA spec and AMD datasheet but it could be that for nVidia hosts
for some reason we need to use the higher timing (or maybe nVidia
has different programming requirements for this register).

Richard, could you try the attached patch?

Daniel, thanks for the link - now it is clear that it is not nVidia specific, however I still wonder whether this is generic IDE problem or the commit just uncovered some problems - in any case I'm going to revert the patch for 2.6.25 (this has the cost of making cable detection less reliable...).

To Ubuntu developers: please help us with letting us know about problems early.  
I'm a bit unhappy with the fact that the issue was initially reported in the beginning of January and I learned about it 2 weeks ago (during 2.6.25 stabilization phase)...

@Bartlomiej : i'm not ubuntu dev, but i'v reported this bug on kernel.org on january 2008-01-28 after reported it on launchpad the 2008-01-09 (the time that i suspect a kernel bug.

@Patrice: Yeah, I know + thanks for reporting it.

The unfortunate thing is that it was all the time under Product: Platform Specific/Hardware + Component: i386 (instead of IO/Storage + IDE).  As a result it never reached linux-ide@ ML or me so we've learned about this bug entry only on 2008-03-16 when the link to the previous bug was mentioned under this bug.

@Patrice: PS could you please re-assign the bug to me.

I was quite puzzled why the same problem is not reported for corresponding libata host drivers as actually the "guilty" change was based on libata changes (+ amd74xx and pata_amd host drivers are very similar nowadays).

It seems that commit f58229f8060055b08b34008ea08f31de1e2f003c ("libata-link: implement and use link/device iterators") which went into 2.6.24 by accident reverted the "guilty" change (thus making cable detection less reliable):

N.B. ata_eh_revalidate_and_attach() gets it right so libata may also be currently affected by the problem but will be triggered only for suspend/resume or if somebody decides to rescan/plug-in devices

I guess that we want to fix libata but at the same time verify that the issue that we've hit with IDE amd74xx/piix does/doesn't happen with pata_amd/ata_piix?

i can confirm that, but i don't have any idea why it works that way

Bartlomiej, thanks for finding out the accidental order change but ata_bus_probe() is deprecated and currently only used by sata_sx4 and SAS.  None of PATA ones uses that path anymore.  Everything goes through ata_eh_revalidate_and_attach().  Richard, can you be persuaded into trying pata_amd?

So, pata_amd works fine.  It doesn't look like the reversed IDENTIFY order is the actual culprit in the probing failure.  pata_amd has been doing it that way for a long time now.  It was converted to new EH pretty early and have been using the reverse order IDENTIFY since it was first applied to EH till now.  I'll forward the fix for obsolete path upstream.  Thanks.

Hi All! Sorry for my ... and for my bad English :-)
Can you see this bugreport please: 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=480679?
This bug was reported to Debian, but it is exact what I have on my Slackware 12.1 with kernel 2.6.24.5. And I can't find it at http://bugzilla.kernel.org. But the key words of dmesg ("hdc: status timeout: status=0xd0 { Busy }  ide: failed opcode was: unknown  drive not ready for command") is equialent to this topic.
Is Debian bug 480679 equialent to kernel bug 10239 or should be reported separately?

P.S. Additionally to Debian bugreport, I have next features on Slackware: 
- not only hald-addon-storage, but k3b also can freeze system;
- trying to renice k3b process that eats ~99% CPU have no results.

This bug as it has been fixed months ago by reverting the change causing regression (sorry for the late update):

[ also in the end it looked like a generic timing issue in IDE code triggered
  by my change - the underlying issue may have been fixed in newer kernels
  (there were a ton of fixes since then) so it would useful if somebody tries

Tejun: feel free to fix (or forward to Alan) the above issue (I'm too busy with other stuff + amd74xx doesn't have the problem)

sergey: please try some recent kernel (preferably 2.6.26-rc6) and if the issue still happens there open a new bug

Patrice: please close this bug
