This one?

http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ab17443a3df35abe4b7529e83511a591aa7384f3

Doesn't it break existing setups without giving ANY warning?

theoretical (I don't have hardware in question) scenario:
- user uses atiixp and has modular libata/ahci (or no libata/ahci et all)
- user does kernel upgrade
- boot fails
- ...

If this is true please add something like

printk(KERN_WARNING "PCI: setting SB600 SATA to AHCI mode"
" (please use ahci driver instead of atiixp)\n");

to quirk_sb600_sata() so people will at least know what is wrong...

> cleaned. Now we remove these code sine they are no use any longer.

[ but the patch is line wrapped and unfortunately doesn't apply ]

PS: please always cc: linux-ide@xxxxxxxxxxxxxxx on PATA/SATA patches

Thanks,

Hi Bart,
I've tried to access the following link to make sure which it is,
but failed. The internet here is almost broken.
http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ab17443a3df35abe4b7529e83511a591aa7384f3

I sent out 2 patches for the same SB600 legacy IDE issue. the later
(sb600 pci qurik) is better so we should clean the previous patch
which was applied to atiixp.c. -- that is what this patch does.

BTW, I re-create and re-send the patch (see below) based on
2.6.20-rc4, in last patch I fogot to rename atiixp.c.1 to atiixp.c
which may lead to patch fail, nothing else different.
And maybe no need to re-ACK if last one is accepted:)
Thanks!
