Is this patch supposed to be applied also on systems with only PATA
drives? My laptop does not have SATA and does not show this bug.

thanks,

The crash will only occur if you have SATA ports on a PIIX chip.
Applying it won't do any harm.

I'll put up a -ide2 today with it folded in

Not really. AFAIK lowest nibble bit has meaning only in DMA mode anyway.

Anything else I could try to help pinpoint the problem?

The BIOS docs are fairly confusing on that point referring to one bit as
the "PIO FIFO" bit.

> Anything else I could try to help pinpoint the problem?

Set the controller to support PIO only and see what happens.

[ie set .udma_mask = 0 i nthe ali_init_one entries]

If that works it implies the DMA tuning may be involved. If that doesn't
change it what happens with a hard disk in the same place ?

I also tried the Tejun Heo patch for 2.6.17 (wihout PM) + pata_ali from Jeff
Garik git tree with the same result; may be it gives more information about
the error:

Hrm, I finally tried a different CF card (Viking 256MB) from the one I
usually use in my camera, and it failed to work:

Ick, apparently I wasn't running what I was thought I was running. It
appears that the only reason pata_pcmcia was working at all was
because I was still using the 2.6.17-rc4-ide1 version of the patch (on
2.6.17 final). The 2.6.17-ide1 version of pata_pcmcia fails like so
(with my usual 1GB Sandisk card):

Yep. There are some uglies with the pcmcia layer. Fixed in the devel
tree for a while
