USB 3.0 problem found: Haswell delayed

When a computer with Haswell processor wakes up from S3 sleep mode, problems can occurs with devices connected via USB 3.0. In practice that could result in Acrobat Reader showing a blank PDF file, or that a video stops playing. To solve this, new hardware is required. Through an official Product Change Notification (PCN) Intel has now confirmed that there really is a problem and that a solution is being worked on. That entails changing the stepping from C1 to C2, which should address the problem of USB 3.0 devices not being recognized after waking from S3 sleep.
This solution will affect the delivery dates of certain products, and according to the PCN that includes the Z87, H87, Q85 and Q87, the C222, C224 and C226, and the QM87, HM87 and HM86.

Could also affect the release time of the new Mac Pro, I'm guessing.

According to the following link, Haswell and 8x chipsets will still be available in limited quantities. The new fixed C2 revision should hit the market sometime in late august...

So there's been a major bug twice in the last three chipset launches. Good going Intel! AMD gets yet another opportunity to catch up, let's hope they don't screw it up again. We really need a strong AMD to get Intel to bring their A game.

That is something is really odd. How in the hell would Intel make their far more complicated CPUs perfectly fine but mere chipsets bug out so much? It makes no sense.

Haswell became even less exciting. Only reason to wait is to hope there is base clock overclocking.

I think they did this purpose.. So they can get out their Ivy E chips.. then late 2013 come with Haswell launch Q4

Intel CPU bugs can be sidestepped via motherboard bios update revisioning. The Ivy Bridge "Intel CPU microcode" is currently on revision #17.
Example here:

Note: this example is a modded bios. The same (version name) of Gigabyte's official beta version bios has the slightly older "Intel CPU microcode" revision #16.
