@ 2013/04/08Intel issued a product-change notification (PCN) to partners in the motherboard industry, informing them of a new C2 stepping of the 8-series "Lynx Point" chipset. The stepping introduces a metal layers change that fixes the USB 3.0 remuneration erratum, which causes devices plugged in to USB 3.0 ports to fail to reinitialize after waking up from sleep states such as S3, requiring uses to unplug and replug them, which could get particularly irritating for people with external RAID devices that rely on USB 3.0 for host connectivity.
According to the PCN, the first socket LGA1150 motherboards in the market may not feature C2-stepping chipset. It predicts samples to be available to motherboard manufacturers by April 19, 2013; availability of qualification data (when Intel has finalized design after taking feedback from partners), by July 1 2013; customers should be ready to receive C2-stepping chips by July 31. These dates indicate that the very first batches of socket LGA1150 motherboards will still feature C1-stepping chipset that are affected by the erratum, and if you can't live with it, you should ideally wait until late-August or mid-September for the first motherboards with C2-stepping chipset to make it to the markets. Intel expects to launch its 4th generation Core "Haswell" processors and compatible LGA1150 motherboards by mid-June.
