Intel Confirms, Fixes Haswell's USB 3.0 S3 Sleep Problems

By - Source: Hardware.info | B 24 comments

Intel has issued a Product Change Notification (PCN) to correct Haswell's USB 3.0 S3 sleep problems.

On March 1st, it was revealed that Intel's upcoming fourth generation "Haswell" processors was having issues when waking from S3 sleep with a device plugged into a USB 3.0 port. Specifically this implementation problem resulted in a number of nuisance issues such as having blank pages displayed in PDFs and video that stops and cannot be resumed.

To resolve this issue, Intel has now issued an official Product Change Notification (PCN) that alters the chipset stepping from C1 to C2, a hardware fix that is expected to affect the delivery dates of a fairly wide range of products. According to the release, this revision includes the Z87, H87, Q85, Q87, C222, C224 and C226, QM87, HM87 and HM86 chipsets. 

When asked for comment, Intel provided the following statement to Hardware.info:

“4th gen Core is on track for a mid-year launch. Intel issued a PCN documenting a chipset USB errata and stating that chipsets with the errata will be in production during the initial ramp. But Intel has confirmed that there is no chance of data loss or corruption.  This issue has only been observed with a small subset of USB SuperSpeed thumb drives and does not affect other USB peripherals. We take all customer issues seriously and should any customer have a question or concern they can always contact Intel customer support.”


Though Haswell's S3 sleep issues all fell in the "nuisance" category and could all be resolved by a simple restart of the affected application, it's excellent to see that Intel has officially acknowledged the problem, implemented a fix and perhaps most importantly, not knowingly put defective products onto the market.

    It that mean we don't have to worry about getting C1.

    Doesn't is seem they have the same sleep issue with every other new generation they come out with?

    I thought this was a problem with the cipsets and not the processors themselves. This article makes it sound like the C2 stepping is being applied to the processors, then in the next sentence the cipsets are actually receiving the revision.

    I assume it means that we shouldn't have to worry about getting any C1 stepping. Though I am not entirely sure, perhaps they will just tack on a "C1" at the end of the model number for a while (until they are out of c1 stock)

    Thats not right, don't go after a good guy like rgd, hes asking a question and its easily discernible as to what he means. I see him helping out people on the forums a lot. Good guy.

    Kudos to Intel for admitting an issue, correcting it and insuring the version with the issue does not hit any customers. A lot of companies would have handled an issue like that poorly.

    Reminds of the serial comm port bugaboo when the P5-60 was released. Never forget the day that behemoth from Gateway showed up and the system froze the minute I eagerly awaited the modem negotiation with Compuserve. Guess I'm showing my age but at least this time they caught it before it shipped.

    It is a chipset issue. Haswell is more well known as a name and since it requires a new chipset it's bundled together. This statement is all you need:
    "To resolve this issue, Intel has now issued an official Product Change Notification (PCN) that alters the chipset stepping from C1 to C2, a hardware fix that is expected to affect the delivery dates of a fairly wide range of products."

    from the PCN pdf.

    Customers should be ready to receive a combination of C1 stepping material and C2
    stepping material by the "Date Customer Must be Ready to Receive Post-Conversion
    Material" as shown in the milestones above.

    more from the PCN pdf

    The date of "First Availability of Post-Conversion Material" is the projected date that a customer may
    expect to receive the new Materials. This date is determined by the projected depletion of inventory at the
    time of the PCN publication. The depletion of inventory may be impacted by fluctuating supply and
    demand, therefore, although customers should be prepared to receive the Post-Converted Materials on this
    date, Intel will continue to ship and customers may continue to receive the pre-converted materials until the
    inventory has been depleted.

    Looks like the author updated the wording in the article without informing anyone, but I guess that's to be expected here. When I originally posted, that first sentence you quoted referred to the C2 stepping as a processor revision, but the following sentence suggested that it was a chipset revision.

    Well, at least we got an update. Can't say the same for most of the poorly worded news articles on Tom's.

    will the i3 Haswell come out at a later date or along with these?

    Look at their SB B2 stepping product recall. That was only on SATA3 and would have effected a small group that thrash the bus. Cost them a lot but they recalled it all.

    The statement from Intel sounds like we'll still get revision C1 as motherboard makers already have them, they're just waiting for the official launch date. IMO revision C2 will not be available for some time until most of the C1 board are sold.

    Incorrect. C1 is already shipped. Whoops. :p 
    mouse24I assume it means that we shouldn't have to worry about getting any C1 stepping.
    Well, that's what you get for assuming. ;) 

    See rgd1101's posts above regarding the PCN documention for more info.
