After some testing, kernels that have ATA_PIIX and SATA_AHCI compiled as
modules do not get timeouts
Work properly
r...@# egrep -i "ahci|ata_piix" /boot/config-2.6.24-25-generic
CONFIG_ATA_PIIX=m
CONFIG_SATA_AHCI=m
Gets timeouts
r...@# 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
root@:# lsmod | egrep -i "ahci|ata_piix"
ata_piix 19588 2
libata 159728 3 ata_generic,pata_acpi,ata_piix

ata timeout exception with ahci libata driver (was with 2.6.28-11, but i
confirmed it affewcts previous kernels too)
