You are using libata driver not IDE one, so I'm reassigning it to libata developers. Are you able to identify an earlier kernel which didn't have this problem? 2.6.22? 2.6.23? Thanks. 2.6.17 from Fedora 6 test 3 works I will test some more kernels. 2.6.15 from Ubuntu 6.06 works 2.6.20 from Ubuntu 7.04 does not work 2.6.17 from Ubuntu 6.10 works 2.6.18 from Fedora Core 6 does not work Created attachment 13884 [details] bug9491-ata_piix-detection-dbg0.patch Can you please apply the attached patch and report what the kernel says when loading ata_piix?

Thanks. How do I do this ? If I remove ahci my root-filesystem goes away. Yeah, it's tricky. If you have another machine, using net or serial console would do. If you have a PATA drive lying around, making a temporary installation for testing on the drive would do too. Can you do one of the two? It`s a notebook, so I can`t add a second harddisk. I can attach a second system to the serial port though. But where does it get me, if I try to remove ahci from the local console or the serial console, both times the root fs goes away. Robert, you can build the kernel with ata_piix built in but not ahci and capture the boot log. The boot will eventually fail due to missing root fs but the log should give us enough info. Hi Tejun, my last serial console is several years ago, but it worked. cu romal Created attachment 14283 [details]

Hi Teju, do you need a bootlog without ahci or something else ? cu romal Yeap, I need boot log w/o ahci. Thanks. Created attachment 14585 [details]

The log is completely garbled. Can you please re-post? Thanks. Created attachment 14614 [details]

Robert, the log is not from the patched kernel. The patch contains debug messages which are always printed for ich6m. Can you please double check you're running the patched kernel? Thanks. Created attachment 14629 [details]
boot.log with missing ahci
Hi,
I patched the driver again and bumped ata_piix version number to 2.99 to see if the patched driver is loaded.
cu romal
Ah.. You're right. I was looking at the wrong patch. Sorry about that. I wonder what the difference is. Perhaps the right thing to do is to disallow ata_piix if ahci mode is enabled and only allow the other way around. I'll prep another patch. Created attachment 14633 [details]
ich6m-ahci-in-ahci-mode.patch
Can you please try this patch? This patch will prevent ata_piix from grabbing the controller.

bootlog with patched ata_piix
Hi Tejun,
what Do you need ? Bootlog without ahci ?
Attached is the bootlog with your latest patch ?
cu romal
Yes, boot log w/o ahci. ata_piix shouldn't attach to the device. Created attachment 14638 [details]
bootlog with missing ahci driver
Hi Tejun,
I don`t see the ata_piix driver loading at all.
cu romal
Hi, anything I can do to help ? cu romal I have a bug report where ICH7 fails to detect a PATA device and am still wondering whether this problem is related to that one or not. It probably isn't related but I'm still not sure. I'll verify few more things before posting the patch upstream. Thanks. Hi, did you got it upstream ?
