Haswell systems face USB 3.0 problem
Intel’s Haswell chip and the LGA1150 platform are still a few months away but the upcoming LGA1150 platform has already faced its first problem – according to internal Intel documents the current Haswell chips face a USB 3.0 hitch.
The issue occurs when a Haswell-based system goes to S3 sleep state at the same moment when data, residing on USB 3.0 devices, gets requested. Later when waking up from S3 state the system may not be able to keep working with the same USB 3.0 data that got requested. Thus a PDF document may appear blank while a movie playing from a USB 3.0 device will be terminated. The good news is that no data loss occurs – instead users will have to open the file again.
Intel says the issue will be resolved in upcoming Haswell revisions but since the chip has been in production for the past few months it is unclear what Intel will do with the already manufactured chips.
