with USB 3.0 controllers integrated into Intel's upcoming "Lynx Point" 8-series core logic can be addressed only with new hardware (modifying the silicon), according to a new Hardware.info report. Intel decided against delaying launch of the 4th generation Core "Haswell" family to address the issue, and instead opted to address it in a future revision of the chipset.
A design flaw causes devices connected to Lynx Point's integrated USB 3.0 controller to be disconnected when the system wakes up from S3 (suspend-to-RAM), forcing users to reconnect them. This could mean you'd have to mount your USB 3.0 hard-drives/flash-drives again, although no data is lost. If you're editing files stores on such a storage device, you might have to save your work before the system is put to S3 sleep.
In 2011, Intel launched its 6-series "Cougar Point" core logic that drove its first LGA1155 processors based on the "Sandy Bridge" architecture; with a faulty SATA 3 Gb/s controller, that warranted a general recall and replacement with 6-series Rev 3.0 chipset. This particular issue is classified by Intel as more of an irritant than a major flaw. It remains to be seen how it affects early adoption of the platform.
