After some testing, kernels that have ATA_PIIX and SATA_AHCI compiled as modules do not get timeouts
Work properly
root@# egrep -i "ahci|ata_piix" /boot/config-2.6.24-25-generic CONFIG_ATA_PIIX=m CONFIG_SATA_AHCI=m
Gets timeouts
root@# egrep -i "ahci|ata_piix" /mnt/hd/boot/config-2.6.31-14-generic CONFIG_SATA_AHCI=y CONFIG_ATA_PIIX=y
This is also true for other kernels on other distros, for example (f10 kernel)
root@:# egrep -i "ahci|ata_piix" /boot/config-2.6.27.5-117.fc10.i686 CONFIG_SATA_AHCI=y CONFIG_ATA_PIIX=y
My problem goes away if I rebuild the kernel with these two as modules and do not load ahci in initrd
