Jan 31 2011 - Intel has just announced a design flaw in the Intel 6 Series chipset (code named Cougar Point). This chipset is used with Intel 2nd Generation Core i Sandy Bridge processors. The actual processor is not affected, only the chipset which is used in motherboards. The affected chipset has been shipping since January 9th and is believed to be confined to quad-core 2nd Generation Core i5 and Core i7-based systems.
The actual design flaw turns out to be within the SATA port and may cause degradation over time. The SATA port can be used with compatible hard drives and CD-Rom drives, which could impact performance and functionality. Intel was forced to stop shipment of the flawed chipset. And while Intel has corrected the problem, it will take some time for the updated chipset to arrive to customers (estimated to be late February).
