Nehalem ebenfalls vom TLB-Bug betroffen.

[Bylar]

TLB, three letters that have destroyed the sales of Phenom and Opterons based on 65nm K10 cores stands for Translation Lookaside Buffer and Intel officialy states in its Intel Core i7 Processor, Extreme Edition Series and Intel Core i7 Processor - Specification Update PDF that the CPU has a TLB bug.

If you open Intel’s official document that is nicely stored here, on page 37 AAJ1 Clarification of TRANSLATION LOOKASIDE BUFFERS (TLBS) Invalidation part, you will see that Intel tells that in some rare cases improper TLB invalidation may result in unpredictable system behaviour and can hang your OS or result with incorrect data. Here is the word to word "In rare instances, improper TLB invalidation may result in unpredictable system behavior, such as system hangs or incorrect data. Developers of operating systems should take this documentation into account when designing TLB invalidation algorithms. For the processors affected, Intel has provided a recommended update to system and BIOS vendors to incorporate into their BIOS to resolve this issue."

Das reine Kopieren von anderer Leute Texten ist hier als Grundlage einer Diskussion unerwünscht. Ich möchte zumindest darauf bestehen, dass der gefundene Text selbst kurz zusammengefasst und mit einer eigenen, begründeten Meinung versehen wird, damit man darüber auch produktiv diskutieren kann.

So wie jetzt geht's aber nicht.
