Theo de Raadt wrote about the Intel Core 2 Duo chip: "Various developers are busy implementing workarounds for serious bugs in Intel's Core 2 cpu. 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." Intel has given a response to the concerns as well.

I've been using dual-core machines since the second shipment of the Athlon X2s. Each of the ones I've used (X2, PPC 970MP, Core Duo, Core 2) has been extremely stable. So IMHO, the claims about errata in these chips are overstated.
In any case, dual core doesn't really make a chip more prone to bugginess. Since the cores are clones of each other, the only additional source of bugs really results from the design of the interconnect/shared cache, which doesn't add that huge amount of complexity.
