This is just a heads up to my SB guys/gals:

A problem requiring a "silicon fix" is bad news in the chipset business, and sadly that's what Intel is announcing.

It only affects the 3Gbps ports. This is a huge bummer. Although I'm not affected since I'm only using the 6Gbps ports, so I don't mind waiting until it all eventually gets sorted out and presumably they ship everyone new motherboards.
Good advice, just make sure its not on an SSD, as the sandforce based models when 'full' get into a settled state of performance.
What to do if you've already received a flawed Sandy Bridge desktop Read more:

From what I've read so far its only affecting the P67's not the H's. See below:

Intel's stock dropped on the reports.
From ASROCKs website..

Yeah it was kinda hard to decipher..
Just found this from a guy @ the EVGA forums..
Just got an e-mail from newegg I'd like to share:
Thank you for giving us the opportunity to serve you. Newegg has recently become aware of a design issue that is affecting recent models of Intel Sandy Bridge platform motherboards. We are working with Intel to identify the exact nature of this problem.
As always, Newegg remains 100% committed to our customers' total satisfaction. In keeping with our commitment to our customers, we are extending the return period for your motherboard by 90 days or until replacements become available from the manufacturer, whichever is greater. Intel expects to have a new revision of the P67 & H67 chipsets out around April, at which point first-run motherboards with this issue will need to be physically replaced in affected systems.
From a technical standpoint, the design issue can be bypassed fairly simply by not using the Serial ATA (SATA) ports that are affected. Your motherboard’s manual should identify your SATA ports by number, and at a minimum you should see ports 0-5 (6 ports in total) listed. Ports 0 and 1 are Sata Rev. III (6Gbps), and do not appear to be affected by this problem. Ports 2-5 are SATA Rev. II (3Gbps) and should not be used. For a thorough explanation of this hardware work-around, please refer to our video on YouTube:
If you choose to use the hardware work-around option, there is no need to contact us at this time. We have your information on record and will email you as soon as the replacements become available. If you would like to discuss this with our tech community or read up on the latest updates, please visit our EggXpert forum:
http://www.eggxpert.com/forums/thread/682006.aspx
If none of the above options are suitable to your needs and you wish to return the board at this time for a full refund, please email us at [email protected] and include your sales order number so we can help you out with your return.
If you have any concerns, please contact Newegg Customer Service for further information and assistance.
Thank you for your support!
Sincerely,
"The Source of Intel's Cougar Point SATA Bug"
AnandTech's article about the nitty-gritty hardware details surrounding the Sandy Bridge chipset recall...
The problem in the chipset was traced back to a transistor in the 3Gbps PLL clocking tree. The aforementioned transistor has a very thin gate oxide, which allows you to turn it on with a very low voltage. Unfortunately in this case Intel biased the transistor with too high of a voltage, resulting in higher than expected leakage current. Depending on the physical characteristics of the transistor the leakage current here can increase over time which can ultimately result in this failure on the 3Gbps ports. The fact that the 3Gbps and 6Gbps circuits have their own independent clocking trees is what ensures that this problem is limited to only ports 2 - 5 off the controller.
You can coax the problem out earlier by testing the PCH at increased voltage and temperature levels. By increasing one or both of these values you can simulate load over time and that’s how the problem was initially discovered. Intel believes that any current issues users have with SATA performance/compatibility/reliability are likely unrelated to the hardware bug.
It sounds like Toshiba connected their hard drives to the Sata2 ports instead of the Sata3 ports in their notebooks. Whoops... seems a bit silly to me, if the Sata3 ports were already there why not use them incase users wanted to go with an SSD later?

Also, Asus has joined Gigabyte in the Replacement or Refund camp: http://event.asus.com/2011/SandyBridge/notice/
I wonder how the refunds will work? I'd gladly keep my board till April then grad a refund and purchase a Z67 board.
