Developers told not to panic over new Intel Core 2 Duo steppings

OpenBSD founder Theo de Raadt publicly denounced Intel’s Core 2 processors on the OpenBSD mailing list. Raadt cited 38 pages of processor errata from Intel’s published CPU specifications (PDF).

“These processors are buggy as hell, and some of these bugs don’t just cause development/debugging problems, but will *ASSUREDLY* be exploitable from userland code," Raadt said. "Some of these are things that cannot be fixed in running code, and some are things that every operating system will do until about mid-2008, because that is how the MMU has always been managed on all generations of Intel/AMD/whoeverelse hardware."

Linux coordinator and former Transmeta employee Linus Torvalds, thought otherwise and considers these bugs “totally insignificant.”

Processor errata is nothing new, Torvalds said. Commodity CPUs such as chips based on the Intel Core 2 architecture have a considerably lower bug rate than proprietary boutique CPUs.

“Yeah, x86 errata get more attention," said Torvalds. "But those things are pretty damn well tested. Better than most.”

The errata document specifically mentions the Core 2 Duo E4000, E6000, and X6800 series processors. None of the errata are nearly as insidious or widespread as more infamous problems, like the original Pentium floating-point bug, although some can lead to buffer overflow exploits, claims de Raalt. All of the current errata have patches in the works or can be — and have been — worked around by developers.

In a statement from Intel Global Communications, Nick Knuppfer writes:

“Months ago, we addressed a processor issue by providing a BIOS update for our customers that in no way affects system performance. We publicly documented this as an erratum in April. All processors from all companies have errata, and Intel has a well-known errata communication process to inform our customers and the public. Keep in mind the probability of encountering this issue is extremely low."

“Specification Updates for the affected processors are available at http://developer.intel.com. All errata are thoroughly investigated for issues and vulnerabilities, should they have any we fix them, usually through a microcode update.”

Fanboys...
How many things in the room you are in have a USA Patent on them? Where would you be if it were not for the US technological revolution our form of government allows? A FanBoy buys into the idea lock stock and barrel of his idol. I already know the answer to the first question, so you must be a USA fanboy, you buy all of our products you can. The best that most any other country can come up with is a thin watered down patent with their own local patent office, or pirated technology (Go your country for stealing!). Remember most all forms of electrical appliances and generators(AC and DC) were patented in the US, most all forms of telecommunications were patented in the US, most all forms of manufacturing were developed and/or patented in the US.

All those who say "USA sux, they should go away" always have to throw an "*" in there which in the fine print reads "But, we get to keep their stuff!" LOL Kill the Goose that lays the Golden Eggs. I assure you the world will be a far worse place if the USA dissappears. Look at Africa. That will be Europe and Asia if the USA goes away. Capitalist Societies (like US, UK, Japan) are the only ones that can survive peace time (China is trying to become capitalist, but can't get there under a communist government. Either their government will change or they will go on a rampage, we'll see). All others have to continually conquer or extort resources to survive. All of the poor countries are empires that the USA will not allow to prey on their neighbors for resources. That is why you (and others from economically challenged countries) hate America. You want to steal from your neighbor so you can live high on the hog for a few weeks then it is off to the next neighbor. Look at history (France, Spain, Great Brittan, Germany, USSR, Japan, Rome, Greece), all of the great empires collapsed once they reached a point that they could no longer get to someone to loot, so they looted their own people till they emploded in revolution or dissolution. The USA consumes a large amount of resources, true, but we pay for them at the sellers requested price, and we produce more for the world than we consume. Our people are well fed (maybe too well) and we go on to feed a hugh percentage of the world (sometimes for free, which I think is wrong, let the lazy starve, only the workers should survive (law of the first American colony))

USA Fanboy indeed. Look at your own country with that same microscope on the same settings. You will see that since the USA was founded it has done more for the world than any other country and continues to do so to date. The End. Your fairy tale is over. Go post on a foreign web site.
