I wonder which motherboards are affected? All?

Santa Clara, we have a problem. That's the message Intel engineers had to deliver to company execs after discovering a "design issue" in the company's 6-Series chipsets. The issue is severe enough that Intel decided to halt shipments while it implements a fix.
"In some cases, the Serial-ATA (SATA) ports within the chipsets may degrade over time, potentially impacting the performance or functionality of SATA-linked devices such as hard disk drives and DVD drives," Intel said in a statement. "The chipset is utilized in PCs with Intel's latest Second Generation Intel Core processors, code-named Sandy Bridge. Intel has stopped shipment of the affected support chip from its factories."
Intel said it has already corrected the issue and has started making a new version of the support chip that doesn't have the design flaw. In addition, the Santa Clara chip maker says Sandy Bridge processors and other other related products are unaffected.
