I didn't notice this before now and I'm not experiencing any problems so I'm just going to ignore it for now :!:

It's a bug of kernel since 3.7.x. All my SATA disk under mvsas controller failed with same error.
I'll keep 3.6.11, and wait new kernel mature. I suspect the new RCU changes break too many things.

I didn't report bug, because I have no time to bisect it, no usable info to report.
3.7.x has another bugs, under vmware 9 with over 4G RAM guest, eval acpi method take long delay. I bisect it to the RCU part, then no result, too many unstable RCU changes in 3.7-rc1.

Yes, it the commit. It's not just a debug info. In my case 6/8 disk under mvsas controller undetected.

my disks are all functioning, it seems, at least in my case, that these warnings are spurious

I have the same output with 3.7.3.

On 3.6.8 it was like this:
Code:
ata1.00: configured for UDMA/133
ata1: EH complete
ata2.00: configured for UDMA/133
ata2: EH complete
ata3.00: configured for UDMA/133
ata3: EH complete
ata6.00: configured for UDMA/133
ata6: EH complete


Since 3.7.0 it looks like this:
Code:
ata1.00: failed to get Identify Device Data, Emask 0x1
ata1.00: failed to get Identify Device Data, Emask 0x1
ata1.00: configured for UDMA/133
ata1: EH complete
ata2.00: failed to get Identify Device Data, Emask 0x1
ata2.00: failed to get Identify Device Data, Emask 0x1
ata2.00: configured for UDMA/133
ata2: EH complete
ata3.00: failed to get Identify Device Data, Emask 0x1
ata3.00: failed to get Identify Device Data, Emask 0x1
ata3.00: configured for UDMA/133
ata3: EH complete
ata6.00: failed to get Identify Device Data, Emask 0x1
ata6.00: failed to get Identify Device Data, Emask 0x1
ata6.00: configured for UDMA/133
ata6: EH complete


All disks seem fine, as far as I can tell.

As mentioned by mbar, this was introduced by commit 65fe1f0f66a57380229a4ced844188103135f37b, which is “ahci: implement aggressive SATA device sleep support.”

Kernel developer Aaron Lu mentions he will fix this later…
Read the whole discussion here: http://lkml.indiana.edu/hypermail/linux/kernel/1210.2/00291.html

According to this information it seems that only my computers AHCI implementation (the AHCI controller or, like, its firmware or whatever) does not support aggressive device sleep – the disks themselves are just fine.
