PROBLEM: (libata) cdrom drive not detected in -mm series

PROBLEM: (libata) cdrom drive not detected in -mm series

[Nelson A. de Oliveira]

Hi!

My USB CD-ROM drive (that is detected as a SCSI drive) is not being
detected on the -mm series of the Kernel.

With a 2.6.18-rc6-mm1 tree and after some bisection work, I've found
that the problem is somewhere on these patches:

git-libata-all.patch
libata-ignore-cfa-signature-while-sanity-checking-an-atapi-device.patch
kerneldoc-error-on-ata_piixc.patch
libata-add-40pin-short-cable-support-honour-drive.patch
libata-add-40pin-short-cable-support-honour-drive-fix.patch
asus-mv-device-ids.patch
1-of-2-jmicron-driver.patch
1-of-2-jmicron-driver-fix.patch
2-of-2-jmicron-driver-plumbing-and-quirk.patch
2-of-2-jmicron-driver-plumbing-and-quirk-cleanup.patch
non-libata-driver-for-jmicron-devices.patch
via-pata-controller-xfer-fixes.patch
via-pata-controller-xfer-fixes-fix.patch
via-sata-oops-on-init.patch
libata_resume_fix.patch

Doing a "quilt push
fail-kernel-compilation-in-case-of-unresolved-symbols-v2" (that is the
patch right before the ones from libata), I get a working Kernel, that
detects perfectly my CD-ROM drive.
With a "quilt push libata_resume_fix" (so all the libata changes get
included), the resulting Kernel doesn't detect my CD-ROM drive.

With the libata things applied I can see on /proc/devices:

(...)
Block devices:
  7 loop
  8 sd
 11 sr

But even with sr_mod loaded, I can't get any /dev/sr0 or /dev/scd0.
Since udev is the same with all the tests and /dev/scd0 is there
without libata updates applied, I think that it's something not with
udev, but with the Kernel.

I am sending attached a diff file against dmseg of a working
2.6.18-rc6 against a non-working 2.6.18-rc6-mm1 and also the config
file that I am using with 2.6.18-rc6-mm1

Please, CC me with any answers, questions, etc.

Thank you very much!

Best regards,
Nelson

s/USB/SATA/, I presume.

Argh... yet another PCS problem.  With whole -mm applied, does adding 
kernel parameter 'ata_piix.force_pcs=1' make any difference?

Please provide the following info.

* the result of 'lspci -nvvv'

* dmesg output with the attached patch applied (on top of -mm).

Thanks.

No. Tried with latest 2.6.18-rc6-mm2 and still not detected.

Applied the patch and sending the output of lspci and dmesg.

Thank you very much!

It seems that we screwed up while making two combined ports handled by
single host.  irq2 for the second port is added but other than that
the second port shared everything w/ the first port including port
flags, port ops and transfer masks.  In your case, this resulted in
the PATA ports handled as SATA ports resulting in misdetection.  I
missed this because combined on my mobo puts IDE port first, so SATA
ports doesn't get PCS check which works in most cases.

Can you verify whether the following patch fixes your problem?

Jeff, this doesn't affect upstream-fixes, so this isn't a showstopper
for 2.6.18.  The only left one is Keith's case but he's on road and
won't be able to test proposed fix till 18th.  I'll try to reproduce
it here.

Thanks.

Looks sensible. I didn't consider that case because in the PATA world
nothing is quite that deranged.

Now it's working! :-D
Full dmesg is attached (I don't know if it's important, but I am
sending it anyway).

Thank you very much!
