Can we please stomp this out before it starts to look like
CONFIG_FRAME_POINTER?

We should define CONFIG_ARCH_SUPPORTS_LOCKDEP down in
arch/[i386|x86_64|s390]/Kconfig and use that in lib/Kconfig.debug.

RE: Wish for 2006 to Alan Cox and Jeff Garzik: A functional Driver for PDC202XX

[Erik Ohrnberger]

Good thing that I googled groups this thread.  I thought that I was the only
one that had this problem.

I've gone from three 133TX2 controllers, 5 80-GB drives in a RAID5, and 3
drives in drive linking (all managed by EVMS) to 2 controllers with just the
3 drive linking drives, and still get the mda_expiry error messages.

Last thing that I've done is to force the data drives to use UDMA2, with the
hope that it'll work around this problem.  May be working, as I've not had
an error in 24 hours of running the system, but then I'm not accessing the
drives either.  They are dismounted to protect the data.  Didn't matter
before, got the errors with just the smartd daemon checking up on the drive
health, but so far so good.

Regardless, count me as another one of the interested parties for a cure.
I've read the thread, and will prepare two current kernels, one using the
PDC202XX_NEW and one using the PDC202XX_OLD configuration options.  I'm
hoping that the PDC202XX_OLD will also resolve this issue.

Any further advice on how to work around this would be greatly appreciated.

Erik.

I made it thus, because it failed to compile on powerpc.

Bartlomiej is the old IDE layer maintainer. I would direct any enquiries
to him about those drivers.

2.6.17 with the libata pata patch from
http://zeniv.linux.org.uk/~alan/IDE has a Promise driver for the PDC
20268 and higher that was written by Albert Lee. There is also a test
driver for the older chips (20265 etc).

To try that build 2.6.17 with the patch and then say "N" to CONFIG_IDE,
"Y" to the SATA options under SCSI and the right controller. It will
move your disks to /dev/sda /dev/sdb etc as it uses the SCSI layer.

RE: Wish for 2006 to Alan Cox and Jeff Garzik: A functional Driver for PDC202XX

[Erik Ohrnberger]

Hate to be a bother, but I think I must have botched something.

Here is what I did:
Downloaded kernel code.  
Applied the IDE patches (http://zeniv.linux.org.uk/~alan/IDE)
	(had to apply the change from ata_data_xfer calls to ops->data_xfer
	(no big deal, I speak C )

CONFIG_IDE is set to N
Device Drives\SCSI device support\Probe all LUNs on each SCSI device: Y
Device Drives\SCSI device support\Serial ATA (SATA) support: Y
Device Drives\SCSI device support\Serial ATA (SATA) support\NVIDIA SATA
support: Y
Device Drives\SCSI device support\Serial ATA (SATA) support\Promise SATA
TX2/TX4 Support: Y
Device Drives\SCSI device support\Serial ATA (SATA) support\Promise SATA SX4
Support: Y
Device Drives\SCSI device support\Older Promise PATA controller Support
(Raving Lunatic): Y
Device Drives\SCSI device support\Legacy ISA PATA support (Raving Lunatic):
Y
Device Drives\SCSI device support\Older Promise PATA controller support
(Raving Lunatic): Y

Build the kernel, put it in /boot etc. and boot it.  The kernel finds the
motherboard IDE controllers and recognizes the two hard drives and the DVD
ROM drive there, but it does not appear to find the two Promise 20269
controllers.  What'd I do wrong?  Should I have applied the kernel-2.6.17
patches from kernel.org before the http://zeniv.linux.org.uk/~alan/IDE
patches?

If I ATA/ATAPI/MFM/RLL support\PROMISE PDC202{68|69|70|71|75|76|77} support:
Y
Then the kernel find the controllers, but uses that failing driver rather
than the SCSI/PATA driver.  Yea, well duhh.  So I can't turn that on.

What tree are you working against. The patches I put up are versus
2.6.17 not -mm. Also check in include/linux/libata.h that
ATA_ENABLE_PATA is defined (its down with the debug options). The patch
should have enabled it however.

I downloaded linux-2.6.17.tar.gz from kernel.org, when extraceted created
linux-2.6.17 directory.  I zmore'd the patch-2.6.17-rc4-ide1.gz file and
noticed that it was working against linux-2.6.17-rc4-ide1, so I renamed
the linux-2.6.17 to linux-2.6.17-rc4-ide1 and zcat | patch -p0.
(Did I do this wrong?  Seemed to apply except for the two function calls
that I had to edit by hand)

Checking include/linux/libata.h reveals that: ATA_ENABLE_PATA is defined.

Thanks for all the help.  I really appreciate it, but hope that it's not
taking up too much of your time.

Get linux-2.6.17-ide1.gz instead of the rc4 patch

Not a problem. I'd like to get to the bottom of the problems you are
seeing and this all helps.

I have a PDC20267 and tried out 2.6.17 + linux-2.6.17-ide1.gz  The
resulting pata_pdc202xx_old module didn't initialize the controller on
boot (via initrd).  Is there some other CONFIG option or linux cmdline
that should be used?

thanks.

No it should find it as soon as you load the module. If the device is
not the primary IDE controller (hda-hdd) you can set CONFIG_IDE = y,
include drivers for your other controller and get some debug info.

Usually "it didnt initialize" reports are from people with mixed old/new
IDE in their kernel or initrd, or initrds missing the required modules.

Stick a printk in pdc_init before the pci_register_driver call and
you'll know for sure if the module is getting loaded. If it is then send
me an lspci and I'll have a deeper look

The PDC20267 is the primary controller, I do not have CONFIG_IDE set.
The issue with my initrd was mkinitrd --with=pata_pdc202xx_old didn't
include sd_mod; setting scsi_hostadapter accordingly in modprobe.conf
took care of this.

Once the kernel booted the system was seemingly starting without any
problems until various services tried to write files to the root
filesystem.  Each write attempt resulted in a "Read-only filesystem"
error yet all filesystems were mounted read-write.

The kernel had a ton of errors:

Thats a speed mistune somewhere in the code. 

Can you send me an lspci -vxx and the information on the drive (or
dmesg) with a "normal" kernel boot and I'll hunt it down.

OK, Success!

I have to admit that without the hint from Mike Snitzer, I wouldn't have put

How about this:

From: Heiko Carstens <heiko.carstens@de.ibm.com>

Add LOCKDEP_SUPPORT config option per architecture.

irqflags-trace support and stacktrace support?
