USB 3.0 problems for Intel's Haswell

[podspi]

How many TLB Phenoms got recalled? How many 1.13Ghz P3s? How many nVidia mobile GPUs? How many ATI and nVidia chipsets?

The list is endless. This is how the industry works.

Just look at software, they got the biggest get out of jail freecard on this planet.

podspi: the only thing 'forcing' OEM's to take a product that has any bugs is THEIR competitors, not Intel. They all want to be first to market, if they can already mitigate the bug they are going to take that market timing advantage every single time. If they don't, their competitor will.

I'm referring to this:

It is worth noting that Intel is requesting its partners to accept this issue, before it will supply them with processors.

While bugs happen all the time in this industry (these things are complicated!), they typically are fixed and the customer is taken care of. This is a rumor, so discussing this at length is probably a waste of time but it says to me that Intel does not plan on making it right with customers who get faulty chips. This typically is not the case in this industry:

The TLB bug was fixed (not well, but it was).

The P3: http://news.cnet.com/glitch-prompts-intel-to-recall-1.13-ghz-pentiums/2100-1001_3-245029.html

nVidia GPUs: http://www.engadget.com/2008/07/02/nvidia-says-significant-quantities-of-laptop-gpus-are-defectiv/ (they took a charge to replace and repair defective units).

Turns out I know how the industry works after all.

So, any confirmation besides the original source?
Wondering why sites like Anandtech or Techreport aren't all over this.

The TLB bug was fixed (not well, but it was).

the TLB bug was fixed with new hardware (B3 Phenom), the B2 they sold had a firmware "fix" that killed the CPU performance, so you basically got a lot less than what you payed for anyway.

this USB 3.0 bug doesn't look to serious, but it may affect many users, I don't really use any USB 3.0 device, only 2.0, but... if you always use some USB 3.0 HD it may be a big problem...

wouldn't ignoring the PCH USB 3.0 and using an external solution (USB 3.0 controller on pcie like it was with z68) solve the problem for now?

still, after the whole cougar point sata II bug I thought Intel would be a lot more careful...

Remember the first batch is desktop CPUs. Might never be a laptop with this bug.

First batch is Quadcore Desktop+Notebook. But it's irrelevant. From what we know the chipset is affected not the CPU itself.

Sleep functionality is important to me (use the computer for TV time shifting so it needs to wakeup/sleep properly; to keep the power bill down)

I'm not interested in buying a project; so I will hold off until a fix........

If this is truly just limited to USB3.0, it seems like there is a pretty straightforward, cheap and low-perf impact workaround- just have the system degrade the link to USB2.0 speeds prior to entering sleep. On coming out of sleep, restore the link to USB3.0 speeds.

This assumes that USB links work similarly to PCIe where speeds can be negotiated/changed as needed.

[edit] it's a workaround, not a fix [/edit]

I follow TR more than I do AT, and TR reported it http://techreport.com/news/24441/report-intel-haswell-suffers-from-usb-3-0-issue

I no longer follow AT like I used to, because of what I clearly perceive as pro-Intel and pro-Nvidia bias. I've removed AT from my Firefox RSS feeds. I tried to double check if AT did report it, and either failed or they didn't report it.
And, the exclusion of this story would be further indirect evidence to that claim of bias. So perhaps that's why Anandtech isn't "all over it".

TR already reported the new chipset revision that contains the fix, just today- http://techreport.com/news/24494/report-new-chipset-revision-to-fix-haswell-usb-3-0-bug

Read TechReport.

But TR just cites other sites, who in turn cite "anonymous" sources. AnnadTech has always made it clear they don't play the rumors game. So what exactly are they supposed to report on if there aren't any valid sources?

"Intel to Launch Core i “Haswell” Platform in “Cautious Volumes” Because of USB 3.0 Issues"

"Haswell for desktop (Denlow platform) looks set to launch with cautious volume in June using the faulty C1 stepping, and then to see a stronger ramp once the glitch is worked out. Still, this is more than we had hoped for in June. Caution in Ivy Bridge units still likely to constrain gross margin for Intel and contacts point to August as the more significant launch period."

LOL, Im waiting for Ivy E grab a 8 core or something.
