Word is out on the street that Intel's mainstream 45nm Yorkfield processors will be delayed for six weeks because of a FSB-related problem that causes the chips to crash in some rare conditions.
Intel hasn't confirmed this rumour yet but according to French hardware site Hardware.fr the problem only affects the quad-core Yorkfields. The new 45nm dual-core chips, the mobile editions and the server chips aren't affected by the problem.
The rumour is a bit weird though as the quad-core 45nm QX9650 processor is already available for a couple of weeks and doesn't seem to have any problems at all but some speculate this could be related to the reason why Intel's 45nm quad-core processors don't play well with the nForce 680i chipset. Some sites claimed Intel was punishing NVIDIA for not allowing them to use SLI but now it's speculated that Intel didn't do this on purpose and that it could be the case that this is related to a bug that Intel didn't discover while testing the chips on their own chipsets.
