Tejun,

I've been having good success using your patches from late September
with a sil3124 pcix sata controller connected to 4 drives.  Ive added
another PM and 4 more drives and connected to port 2 on the card.
However on these 4 additional drives I consistently get these errors
when doing any disk IO (reading or write) (no errors on the first 4
drives of which all 8 part of a single software raid array).  Ive tried
2 new eSATA cables, reseated the drives, etc, with no luck.  Any ideas?

Thanks,
Jon

Now that the speed of this drive has been at 1.5gbs, the error has not
returned under moderate disk load for 20 or so hours.  This is odd
because 7 other drives on the same controller are working at 3.0gbs.

Hmmm... Status register value is weird here.  It's reporting device
error via SDB FIS but ERR bit is not set in the status register.

This is collateral damage.

Ah, okay.  Receiving SDB FIS confused the controller.  This is a erratum
of the controller.  If error occurs while commands are in flight to more
than on device, the controller gets completely f***ed up.  This is
probably why the status and error registers are not updated correctly
above.

[EH kicks in and cleans up]

Okay, again, the same device reporting device error and commands only to
the device were in flight so the controller updated status and error
correctly.  The device is reporting ATA bus error.

[again, EH cleans up]

And the same thing one more time.  Note that link is still 3Gbps.

One more time.  EH had enough and limited link speed to 1.5Gbps.  Did
error repeat after this?

Possibilities...

1. The disk or the connector on that slot is faulty.  You can find out
by swapping disk positions and see where the error follows.

2. The specific disk model and the PMP don't like each other at 3Gbps?

Solutions...

1. If the disk is faulty, exchange.

2. If the slot is faulty, exchange.

3. If the disk has dip switch to limit PHY speed to 1.5Gbps, put it on.
 You will hardly lose anything.

Thanks.
