Intel Explains the Core 2 “Problem”

Earlier this week, we posted that a hotfix had been released to handle an issue with most second-gen Intel Core processors. At the time, nobody seemed to understand exactly what the problem was, but it turns out it’s really nothing at all. Certain code could lead to memory leaks, and this is what the fix took care of. However, up to now the cases of this happening have been quite rare, so being alarmed is not necessary. Your next BIOS update should take care of whatever issue is there, though you might never have noticed the difference anyway.

The errata itself has something to do with Translation Lookaside Buffers, also known to this world as TLB, part of the microarchitecture that is improving access to system memory as much as possible by keeping refences to physical memory in its own table.
