Legit Reviews reports Gigabyte is the first motherboard maker to confirm that they have stopped shipping all of their Intel 6-series motherboards until Intel starts shipping new P67/H67 chipsets without the SATA flaw. This may take up to six weeks and at this point it's still unknown how current owners of 6-series motherboards will have to fare.
If you already have a board hold tight as Gigabyte is figuring out what to do right now. Gigabyte is planning on doing some sort of RMA for users that have one of these new boards. If we had to guess those of you that have one of these boards should sit tight a month or two until Intel gets production ramped up on the fixed 6-series chipset.
Gigabyte: For the 6-series boards, we have stopped shipping boards out from our warehouse. All our sales has informed all our channels/resellers/distributors to stop selling the 6-series boards. The management is discussing with our HQ to find out more detailed solutions and will keep you updated later today.
