           Summary: PLEXTOR DVDR PX-740A drive not ready for command
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.25-rc5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: IDE
        AssignedTo: io_ide@kernel-bugs.osdl.org
        ReportedBy: richard.genoud@gmail.com
                CC: bzolnier@gmail.com


Latest working kernel version:2.6.23
Earliest failing kernel version:2.6.24-rc1
Distribution:N/A
Hardware Environment:
MB : ASUS A7N8X-E deluxe
DVD : PLEXTOR DVDR PX-740A (FW 1.02)
Software Environment: N/A

Problem Description:
During kernel boot, the DVD drive initialisation fails with those errors
(2.6.25-rc5):
hda: status error: error=0xd0 { Busy }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status error: error=0xd0 { Busy }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status error: error=0xd0 { Busy }
ide: failed opcode was: unknown
hda: drive not ready for command

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).

I bisect to find out where the bug was and I found that this commit is:

b140b99c413ce410197cfcd4014e757cd745226a is first bad commit

    ide: change master/slave IDENTIFY order

    Need to probe slave device first to make it release PDIAG-
    (this is required for correct device side cable detection).

    Based on libata commit f31f0cc2f0b7527072d94d02da332d9bb8d7d94c.

    Thanks to Craig for testing this patch.

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:

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.

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.
