I'm guessing that your CF-to-IDE adapter doesn't have the correct lines 
wired up for DMA to work properly, and the card indicates DMA support, 
which libata tries to use but which doesn't work. It looks like it never 
tried falling back to PIO after DMA failed. Seems like a deficiency in 
the speed-down logic?

You are right, seems no dma lines in adapter. hda=nodma helped, no errors 
anymore. I will try now also libata_dma_mask and will mail result. Btw there 
is no notes in Documentation/kernel-parameters.txt about it.

In any case it is complete board, WRAP.2C made by PCEngines in 2003. Kind of 
popular and mass produced, before was widely used by StarOS, probably known 
GPL violator, who didn't bother himself to supply patches, but at same time 
used it in his projects.

If it is valid for all board with this revision, maybe it is better to put it 
in some kind of fixup/quirk/black list, or how it is called?

"ATAPI Write-once device"  ???

That cannot be correct (??).  Is this with hdparm-7.7 (latest sourceforge) ??
Can you show us the "hdparm --Istdout" output as well, please.

thanks.

Yes latest hdparm-7.7. But maybe it is related to git kernel? Cause lines

CFA spec requires 848a in word[0], not 844a, which explains
why hdparm thought it might be ATAPI.  I've updated my hdparm
source to detect this for hdparm-7.8 (unreleased).
That card (16MB) is definitely buggy.
But your other (1GB) card looks fine.

Thanks.  Somebody else may help with the libata issue.

848A is the preferred configuration value

The use of 044A is also allowed in the case of it being non-removable.
Guess someone got muddled up in the middle.

844A is a bit iffy and it should still be detectable as Word 83 bit 2
should be set ?


As to the old IDE (not libata ?) issue - I suspect a convertor without
DMA support as a first guess.

This is another flash (1GB probably original Sandisk), 16MB one is called 
SHARP, and it is 2-4 years old. Maybe it is some noname with incorrect 
identification data. But it works well in USB card reader.

If this is applicable...  FWIW hdparm was only recently (in past <72

Woo-hoo!

Re: SC1200 failure in 2.6.23 and 2.6.24-rc1-git10

[Denys Fedoryshchenko]

I am using Gentoo (and it is custom build of linux, actually only busybox + 
kernel + uclibc and few other tools), hdparm is vanilla 7.7

I will try to compile now -rc2 to see if there any changes.

With 16MB 2.6.24-rc1 works fine, 1GB working also with some errors in dmesg. 

And IF that all is important, cause it is relatively old hardware and 
probably if it is only this hardware-specific bug, it is enough to issue 
workaround just to be able to use it. I dont think so someone using them now 
much, but IMHO things must work in kernel if they are there.

Please try booting with "hda=nodma".

It could be a hardware problem (CF adapter without DMA lines).

Re: SC1200 failure in 2.6.23 and 2.6.24-rc1-git10

[Denys Fedoryshchenko]

Does it work as kernel parameter?

I tried libata_dma_mask=0x4 and to set 0xf or 0xff - doesn't help. How to 
disable DMA in libata, if it is compiled in kernel?

libata.dma_mask=3

will leave you with CD and disk DMA but not CF DMA

It's "libata.dma" if its built into the kernel, or 'dma' module option
if built as a kernel module.

Thanks, it works like that.

Seems in libata there is no fall-back to non-DMA mode, if DMA didn't work.

It should be falling back from UDMA or MWDMA to PIO, if not please file a
bug

There is, it's just too conservative about that.  With improvements
pending for 2.6.24, it should be quite snappy at falling back to PIO if
configured transfer mode doesn't seem to work at all (consecutive IO
command failures after transfer mode configuration change).
