Re: [PATCH] speed up SATA: Bug?

Hi...
Applied the patch to 2.6.5.rc-2, got these errors after recompile/reboot 
(from dmesg):-

VFS: Mounted root (ext2 filesystem).
SCSI subsystem initialized
libata: Unknown symbol pci_dma_mapping_error
sata_sil: Unknown symbol ata_std_bios_param
sata_sil: Unknown symbol ata_tf_load_mmio
sata_sil: Unknown symbol ata_bmdma_start_mmio
sata_sil: Unknown symbol ata_tf_read_mmio
sata_sil: Unknown symbol ata_exec_command_mmio
sata_sil: Unknown symbol sata_phy_reset
sata_sil: Unknown symbol ata_check_status_mmio
sata_sil: Unknown symbol ata_interrupt
sata_sil: Unknown symbol ata_scsi_slave_config
sata_sil: Unknown symbol ata_fill_sg
sata_sil: Unknown symbol ata_std_ports

sata_sil: Unknown symbol ata_port_stop
sata_sil: Unknown symbol ata_pci_remove_one
sata_sil: Unknown symbol ata_device_add
sata_sil: Unknown symbol ata_port_start

Any ideas?  This is an Asus A7N8V Deluxe mobo, NForce2 chipset and a 
Maxtor SATA disc (Model=ST3120026AS).  I have the SIS 3112 ATA chipset 
(compiled in ATA support) and Silicon Image SATA support compiled in 
SCSI low level drivers.

I can post any more information you want.

Phil.

You're system needs to load the "libata" kernel module, that provides 
these functions.

Looks like you're doing "insmod" when you should be doing "modprobe", or 
your mkinitrd is broken, or something like that.
