SATA disks not found after upgrade edgy - feisty

I can confirm this bug on toshiba g20.

It seems that when ata_piix is loaded before ahci, ahci module will not see harddrives correctly.
This helps from initramfs shell:

rmmod ata_piix
rmmod ahci
modprobe ahci
exit

I resolved the problem by blacklisting ata_piix module in initrd image. It seems it is latter loaded correctly (latter in boot, when system already chrooted)

Also it seems it is duplicate of bug: #139790

Still present after clean Gutsy install. Blacklisting ata_piix as suggested in bug 139790 does not work for me; I have to wait for the boot to fail and drop to a busybox shell. Is there any workaround to allow the machine to boot normally?

Also can this bug be upgraded from status New? Issue has affected both Feisty and Gutsy.

Thanks & Regards,
Steve.

I confirm this bug on my toshiba G20, and I can't solve it. How shall I do?

Well I've got some additional info:

In kernel 2.6.23 the problem is still present (compiled with master kernel thread instruticons) but this time bug is less obviouse.
With kernel 2.6.22 and 2.6.20 chances to successfull boot were about 5% (guess the correct order of modules loading)
in kernel 2.6.23 chances of unsuccessfull boot are about 5% - this is progress. I will try kernel 2.6.24 from sources soon.

Also: this is forum thread that I described solving the problem: http://ubuntuforums.org/showthread.php?t=551435

Thanks for your report. Is this still an issue with the latest release ?

issue does not persist in ubuntu hardy, so I guess it just solved automagically.

thanks for following up. I'm closing this report due to your last comment.

Amazing! I've just opened my mail to search for an email from Baronek
with the commands to remove ata_piix as I've just done a clean install
of Hardy on my Toshiba Qosmio and the disks have not been found after
the post-installation reboot.

Regards,
Steve.

I'm going to check this Qosmio machine better soon and I will report back, why it's exactly working. But as far as I remember it just 'worked'.

reopening.

Please, can you boot with the livecd and run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

Thanks in advance.

I'm merging this report with bug #139790 because "workarounds" are better described in the other one. Please attach the previously requested information to the other report. Thanks.

Thanks & Regards.
