[ltp] ata_piix on a t42p

[Carlos Moffat]

Hi,

I have a t42p and I'm trying to make the switch to the ata_piix drivers
by following the instructions:

http://www.thinkwiki.org/wiki/How_to_configure_and_use_libata_SATA_/_PATA_drivers

I have: 

* recompiled the kernel (2.6.22)
* changed /etc/fstab to use labels 
* changed /boot/grub/menu.lst and switched /dev/hda1 to /dev/sda1 for
this kernel. It reads:

root=/dev/sda1 ro acpi_sleep=s3_bios atapi_enabled=1


When I reboot, I get a kernel panic:

cannot open root device "sda1" or unknown-block(0,0)

(or something very similar). somebody in IRC suggested the problem might
be the T42p chipset might not be supported. 

Does anybody have any ideas, or a working setup with this drivers and a
t42p?

Thanks!
Carlos
