[PATCH V7 2/5] ahci_plt Add the board_ids and pi refer to different features

[Richard Zhu]

On imx53 AHCI, soft reset fails with IPMS set when PMP
is enabled but SATA HDD/ODD is connected to SATA port,
do soft reset again to port 0.
So the 'ahci_pmp_retry_srst_ops' is required when imx53
ahci is present.

[PATCH V7 1/5] AHCI Add the AHCI SATA feature on the MX53 platforms

[Wolfram Sang]

Hi Richard,

again, please use --cover-letter when sending a new series and say
what has changed since last time. Otherwise you force reviewers to find
out for themselves (which easily makes them ignore the series)

Regards,

   Wolfram

The good news are that I have tested this patch series on i.MX53 LOCO
board and it seems to work fine here. Thanks.

[PATCH V7 1/5] AHCI Add the AHCI SATA feature on the MX53 platforms

[Eric Miao]

Hi Hector,

I don't have this issue either. Could you verify it's caused by something else?
You may try a different SSD.

Currently testing with probably same checkout of imx-features branch
with a sata 3.5" drive. Running badblocks in non destructive write mode
and so far, so good (it's slow but it may comes from my drive).

Did you test if there was a bad cable or faulty drive PSU ?

[PATCH V7 1/5] AHCI Add the AHCI SATA feature on the MX53 platforms

Here is my complete dmesg. The system seems to work fine, it is a
1.0TB WD10TPVT SATA disk in a case which provides eSATA and connected
to mx53 LOCO with eSATA-to-SATA cable. I have around a Lacie eSATA
disk which I might attempt to connect.

I think I had a bad configuration setup for my kernel. I have rebuilt
3.1.0-rc6 from Sascha's master git with this patches and now SATA is
working properly I do not see any issue as I did. So, from my side all
is OK now, and I assume I had some missing or conflicting module
setup.

Kind regards and apologies for inconveniences,
