Hi,

Since I updated to 2.6.22 everything has been slower and I think this
is the reason:

ata_piix 0000:00:1f.2: version 2.11
ata_piix 0000:00:1f.2: MAP [ P0 P2 IDE IDE ]
ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 16 (level, low) -> IRQ 16
ata_piix 0000:00:1f.2: 0x1F0 IDE port busy
ata_piix 0000:00:1f.2: 0x170 IDE port busy
ata_piix 0000:00:1f.2: no available legacy port

I tried to apply the patch d583bc18812f8da52bf25eef9cd111e5fd46a6ab,
but I get a similar error:

ata_piix 0000:00:1f.2: version 2.11
ata_piix 0000:00:1f.2: MAP [ P0 P2 IDE IDE ]
ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 16 (level, low) -> IRQ 16
PCI: Unable to reserve I/O region #1:8@1f0 for device 0000:00:1f.2
ata_piix 0000:00:1f.2: failed to request/iomap BARs for port 0 (errno=-16)
PCI: Unable to reserve I/O region #3:8@170 for device 0000:00:1f.2
ata_piix 0000:00:1f.2: failed to request/iomap BARs for port 1 (errno=-16)
ata_piix 0000:00:1f.2: no available native port

I think I'm not the only one with that problem:

Any hints?
