[citation][nom]nurgletheunclean[/nom]It is a chipset issue. Haswell is more well known as a name and since it requires a new chipset it's bundled together. This statement is all you need:"To resolve this issue, Intel has now issued an official Product Change Notification (PCN) that alters the chipset stepping from C1 to C2, a hardware fix that is expected to affect the delivery dates of a fairly wide range of products."[/citation]
Looks like the author updated the wording in the article without informing anyone, but I guess that's to be expected here. When I originally posted, that first sentence you quoted referred to the C2 stepping as a processor revision, but the following sentence suggested that it was a chipset revision.
Well, at least we got an update. Can't say the same for most of the poorly worded news articles on Tom's.
