[SATA] Does SATA work with kernel > v2.6.25.7?

[Olivier Croset]

Hello everybody,

I'm working on a custom board with a Freescale 8347 CPU and a Silicon Image
SIL3512 SATA controller, which is on the PCI bus.

SATA is working with 2.6.22 but no more with 2.6.30.4. I tried different
parameters in the kernel configuration with no success. I got the following
output when Linux boots:

<snip>

 unable to read partition table
sd 0:0:0:0: [sda] Attached SCSI disk
<snip>

Then, I can see /dev/sda but not /dev/sda1 (the partition actually exists).
I can get hard drive informations with hdparm -i and -I.

While browsing the web, I found the following message with the same kind of
errors:
http://linux.derkeiler.com/Mailing-Lists/Kernel/2009-03/msg08159.html

It is said that "the sata is only supported up to 2.6.25.7". Is it true for
all PowerPCs or only for 460EX CPU?

If SATA should work with 2.6.30.4, may I ask you to take a look to my config
file? (http://pastebin.com/f16067607)


Thanks,

Olivier

This messages is explicitly about (and only  about)  the  AMCC  460EX
Canyonlands board and the Synopsys DesignWare Cores (DWC) SATA driver
used on this processor.

This has nothing to do with your poblems with a SIL controller.

Best regards,

Wolfgang Denk
