Bug Description

Binary package hint: kernel-image-2.6.20-9-generic-di

Ubuntu 6.10 installs fine and the laptop SATA chipset is handled correctly by kernel 2.6.17 through ahci driver.
The problem arises with 7.04 Herd5.
The disc is not found in the installation procedure.
A workaround is:
modprobe -r ata_piix
modprobe -r ahci
modprobe ahci
At this point the disc is found and the installation process can go on,
BUT when the system reboots no disc is found by the installed kernel, so the system is unusable.
I suspect that is a Toshiba BIOS bug: there is no switch to choose the chipset ahci compatibility mode. Actually the chipset works in ahci mode but the kernel (at least the 2.6.20 kernel shipped with ubuntu) tries to handle the chipset with ata_piix driver and that fails.

Can you save away a copy of "lspci -vvnn" from the installer and attach it to the bug report?

Cheers,

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
