According to a report over at Hardware.info that managed to get their hands on an internal Intel document, it appears that Intel’s Haswell platform might have a problem with its USB 3.0 host controller.
Although it is not as serious as the Cougar Point SATA 3Gbps bug, the USB 3.0 controller on Haswell platform will have issues with the S3 sleep mode and devices that are connected via USB 3.0 port. Apparently, when waking from S3 sleep, applications that are accessing the data from, for example, USB 3.0 storage device might freeze and force the user to reopen them manually.
Thankfully, the bug will be more of a nuisance rather than a problem as any loss of data is excluded. Intel does not plan to delay the launch and it is still scheduled for mid-2013, according to an Intel representative comment for Hardware.info. Intel is apparently still researching what other consequences this issue could possibly have and plans to resolve the problem in a future CPU stepping.
