Added VT-d to the title, as this is one of those threads that will probably explode

It's one thing for "errata" to be discovered some time after a product has been released and then to manufacture a revised processor, but it doesn’t seem right for Intel to release processors with a known major feature fault like this, especially as most buyers are unlikely to know about it and Intel is even less likely to shout about it.
it is entirely reasonable to assume that it will be errata free.
for a flagship product, especially a flagship INTEL product, it is entirely reasonable to assume that it will be errata free.
also, one of the key roles of SB-E is for hardware virtualization. without it, it can be argued that they are entirely worthless, since a good portion of its users will be using them to run VMs exclusively.
Not sure if serious.
Name one CPU that is errata free.

Wow get a grip, if you look over the changelogs for the steppings of any CPU you are going to find they fix numerous(usually over 50-100) bugs with every stepping and revision. There is no such thing as a errata free CPU.
fine then, let me rephrase: it is entirely reasonable to expect intel to release a flagship product that has all of its features enabled.
happy now?
I love how sites use this to make it sound like its such a bad thing.I dont even think vtd is supported on regular sandys and is a xeon feature.

and Im sure intel is not even mass producing anything yet so they dont need to throw anything away.
vt-d is supported on some sandy bridge CPUs. curiously enough, it is supported for the 2600, but not the 2600k, same for the 2500 and 2500k.
sneaky intel!!!
they lock it out of overclocking power houses to force people that need it to buy higher core count xeons.
If a 2600k had it eneable and were overclocked to 4.7 ghz it would mop the floor with a quad core xeon using vtd
see thats eacltly what I ment about sites that spin this crap,Everyone with a 2600k doesnt even have this feature period and you prolly would never use it or known about it if it wernt for the problem on the new sandy e's
Ill bet the first 6 cores will have it locked out also to keep people paying extra for the xeon version of the chip to use it.
All CPUs have errata, I think there's even some place on Intel's site where you can go and look up all the known errata for their CPUs. Many errata don't even bother getting fixed because they're very unlikely to be reproduced during normal usage and won't ever affect 99.99% of users. Wouldn't be surprised that was the case for the VT-d erratum on SB-E, you'd think if it was a major bug it would have been caught before production silicon.for a flagship product, especially a flagship INTEL product, it is entirely reasonable to assume that it will be errata free.

What is this BS? No more XP drivers for X79 platform? MS still supports XP SP3 until 2014. It's a supported platform. Yet Intel doesn't want people to use XP on their hardware any more???There is some good news however. For those wanting to continue using Windows XP, the Waimea Bay platform will be compatible with both 32-bit and 64-bit versions of the operating system. However, Intel won’t be providing Rapid Storage drivers for 32-bit XP, which means that the basic Windows drivers will be handling drive access, which may not be optimal. Unsurprisingly, the upcoming Waimea Bay platform will also be supporting the upcoming Windows 8, when released.
maybe vt-d can limit the overclocking capability of a chip. after all, it is one extra feature to go wrong. it might also be hard to test for stability in an overclocked chip. last thing we need is a bunch of pseudo-servers with wonky IOMMU support.
but then again, this is intel we are talking about, the king of sometimes dubious product segmentation schemes.
Read this in the comments from that site. Makes sense to me, its a non issue.

This part of the "news" is your own addition and has a nice scent of bias. You can say that it's your own analysis of the news bit on VR, but there are a few flaws with it.
The most important thing to note is that VT-d is not present on desktop platforms. Not only the CPU has to support VT-d, but also key motherboard components (NB/SB). On desktop consummer products these "features" are disabled. They are also disabled on desktop consummer CPUs.
Enterprise customers are not "most buyers" and they do know exactly what features they need and what they don't need. Also they would not normally buy a consumer grade desktop computer. They will buy enterprise grade workstations and servers, which is the Xeon brand, with Xeon compatible motherboards that will support VT-d if they indeed need this feature.
Games, like "first person shooters", are not an really what servers are for. Your trying to plant an idea in the minds of gullable TPU readers (I really hope they buy Bulldozers, I don't want them on the Intel camp), that SB-E has some major flaw that will affect their gaming performance. In reality this doesn't concern anyone since VT-d is disabled at the hardware level on consumer grade desktops.
So why is a bug in a disabled feature important? It's not.
By the time we get Xeons in the channel, they will all be C2. There will be no need for any recalls and "free replacements".
Sorry to lash out like this, but I thought TPU was above this.
