There's some bad news coming out of the cracks of the Internet today, with Hardware.info reporting that they have talked with a "reliable source" who says that the next-generation processor from Intel named Haswell, is having issues with USB 3.0.
The site claims they've taken a look at a document that Intel reportedly sent out to inform system builders of a bug surrounding USB 3.0 and Haswell - the bug specifically has issues with waking from sleep and using a USB 3.0 device. If the system exits S3 level sleep while a user is accessing data on a USB 3.0 drive, their session with that data will end.
This would mean if you're working on a document open before you put your PC to sleep, or it went to sleep after a period of time, when you come back that document could be just blank. Intel is reportedly aware of this issue and are said to be trying to make partners accept the flaw before purchasing the affected CPUs.
The chipmaker is also said to be working on a fix that would slide into a later CPU stepping.
