Include support for SATA FBS(FIS-based switching)

[Shane Huang]

SATA AHCI controller like AMD SB800 support FBS(FIS-based switching),
which can be used to improve the performance for SATA PMP(Port Multiplier).

SATA FBS feature has been added into kernel 2.6.34:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d6ef31539d715db7a0eb2d67a1a008c9d8ccf059
And a bug fix patch has been submitted to kernel upstream:
  http://www.spinics.net/lists/linux-ide/msg37076.html
which has been accepted:
  http://www.spinics.net/lists/linux-ide/msg37109.html

Is it possible for you to add this FBS feature into Ubuntu 10.04?
So that end users can benefit from it.

The bug fix patch has been accepted, which mean these two patches
need to be added to support SATA FBS, can you help to add them?

Hi Shane,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 540749

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
