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.”

You need to think for yourself and stop listening to the media period. War is hell. Civilians die. Deal with it. The allies killed over 50,000 people in one day in WW2 and nobody even blinked. That's what happens when you put military installations and soldiers in a civilian city.

There seems to be this misconception that war can be waged without civilian casualties. This would only be true in an ideal world where both militaries faught on open empty ground. Realistically militaries especially in the middle east, put their installations, munition dumps, and soldiers right next to schools, hospitals, religious shrines, and in densely packed civilian neighborhoods.

If you want to put a munitions dump in a crowded neighborhood, don't scream when I drop a 500lb bomb on that sucker and turn three blocks into a flaming pile of rubble.

I don't really want to call them terrorists because while they are, so technically are we during war times. We use the "Shock and Awe" form of terror which is typically quite effective. Terror is a very effective weapon when wielded properly. I will instead call them Guerillas. These guerillas are masters of controlling the media, they put their installations and bases of operations intentionally near civilian targets knowing full well if we attempt to take them out, civilians will be killed in the process. They did this knowing what would happen, they did it so they can get a news story published on CNN, or BBC, or (Insert your favorite news agency here) that says U.S. Air Strike kills 15 civilians.

This sort of thing is rampant.
World War 1- 9 Million Civilians Dead
World War 2- 47 Million Civilians Dead
Vietnam War- Estimated 4 Million Killed
Korean War- 850,000 Civilians Dead

US Military Casualties
World War 1- 116,708 Killed
World War 2- 407,300 Killed
Vietnam War- 38,218 Killed
Korean War- 33,686 Killed

Take a good hard look at those numbers. Iraq is childs play next to the previous wars we fought.

I would hope whoever coined the phrase, "war is hell," did not mean it to be apologetic.

Indeed. The mere fact that we have gone to war in the past and that those wars have been far uglier than this current Iraq war by no means justifies this war or this administration's laughably and grossly spurious pretexts for it.

If the war were truly necessary and serving a purpose other than that of making a handful of people very rich, then the casualties caused by U.S. soldiers would perhaps be acceptable, but since this war is nothing more than perfect squandering of money, resources, human life, peace, and happiness, these casualties, serving no high or great purpose, are completely unjustified and criminal; in light of this, the patriotic (I absolutely HATE this word!) thing to do is to protest this war and to speak out against those who have made it their emprise to make money through it - such as Bush, Cheney, many others in the white house, leaders of oil companies, leaders of weapon and armour manufacturing companies, etc...

this may be true, but many people still regard WW II as the last 'good' war-==none of these wars were actually started by America

As for criticism--people have criticised the government many times--just watch Vietnam War vets burning their medals or throwing them away--just because they thought that the war was unjust---whenever a bill is vetoed---either by the House/Senate/President--it's in efefct a critique of the government's proposed actions---these criticisms made its way into the constitution way back in 1791 through the Bill of Rights---which is in effect a critique of the powers of the government

Also, you should not forget that actually attacking civilian targets on purpose has great effect when trying to force a nation to the things you want them to do. Just think about the bombs on Hiroshima and Nagasaki: they were civilian targets too, but it did put an end to WW2 by forcing Japan to capitulate.
