SATA HSM error

SATA HSM error

[Rune Torgersen]

Hi

I get the followin gerros once in a while on 2.6.18, running on a
Freescale 8260 PPC.
The controller is  Silicon Image SiI3124 , and the drive a seagate
NL35.2 drive

Any idea if this is hardware or software?

The driver says that the attached device is setting spurious command 
active bits.  I have never seen this before.

SRST doesn't really recover the device but hardreset does.

As it's the first report of this kind, I'm more inclined to hw problem. 
  Can you test with different drive?

Thanks.

I have only seen this on this particular drive so far.

I will shortly.
