Initio 162x SATA controllers

Initio 162x SATA controllers

[Johan van den Berg]

I have run into the same issue as reported before and as is well known  
and discussed on this list:

ata14.00: ERROR: This driver doesn't support LBA48 yet and may cause
                data corruption on such devices.  Disabling.

Commenting out the LBA48 check and actually testing the driver did  
confirm that the driver causes problems:

I have read up as much as possible to start looking into hacking the  
driver to support LBA48. Any pointers / suggestions before I start  
bumping my head?

I am an experienced linux programmer with a lot of unpolished skills  
in kernel development.

I really need to get my drives working...

lspci -v produces the following:

Tejun committed an updated driver to the devel tree so if you pull the
current git trees you should be able to get it to work.

Thanks Alan

I have pulled the latest git and can confirm (via some reading of the  
code) that I have the latest patches for the inic162x  as modified by  
Tejun Heo.

I have now compiled and installed 2.6.26-rc1.

My boot disk is also SATA though and connected via an onboard intel  
chip (00:1f.2 IDE interface: Intel Corporation 82801EB (ICH5) SATA  
Controller (rev 02)) which requires the ata_piix driver.

On RHEL5 2.6.18 I am able to boot off ata_piix but not access the  
inic162x, and on 2.6.26-rc1 I am unable to access ata_piix hardware  
but inic162x seems to work.

The issue I am experiencing with ata_piix is identical to: http://www.nabble.com/-2.6.18,19--SATA-boot-problems-(ICH6-ICH6W)-td7799939.html

Any directions would be appreciated.
