FONTEDevelopers 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.”
vá lá discutam sobre isto
uns dizem que estes bugs podem ser o nosso fim (exagerando)
e aqui o nosso amigo Trovalds partilha da minha opinião que tal coisa não é assim tão grave e que é normal..
