sata_mv driver on 88sx6041 (kernel version 2.6.13)

sata_mv driver on 88sx6041 (kernel version 2.6.13)

[Narendra Hadke]

Hi,
I am using sata_mv driver as exists in kernel 2.6.13,
reached to a stage where after detecting the disk,
control gets struck. Any ideas? 
  I see this driver is modified a lot in latest kernel
version. Will it help to patch with latest changes.
Apreciate your help.

Here is the log:

No surprises there.  The sata_mv driver is horribly buggy
in all kernels prior to 2.6.16, and even there it still has
some serious bugs.  The 2.6.17 kernel version is MUCH better.

Cheers

Thanks. 
I moved further with the 2.6.20 sata_mv driver. Here
are the excerpts from dmesg with ata3 error messages
as follows:

  What is the significance of the

 I am not able to get to the drive as attach is not
happening yet.
Thanks for the help.

Hi,

  In the latest driver sata_mv for 88SX6041, the disk
 is detected but I don't see any attachs happening on 
 this disk ie. something like this.
  Attaching :scsi sda sda1 sda2
    Did I miss anything in kernel configs?  
Thanks
Narendra

Re: sata_mv driver on 88sx6041 (kernel version 2.6.14)

[Narendra Hadke]

Got it working. Thanks.
This works in PIO mode hence performance is horrible.
I see the udma mode is set to 0 in driver 2.6.14
sata_mv version 0.12.  Is is possible to Back port
sata_mv from versin 2.6.17 to 2.6.14 to get a stable
drive. 
   Please let me know.
Thanks,
Narendra
