"(..)Intel finds flaw in Sandy Bridge chipsets, halts shipments
by Cyril Kowaliski and Scott Wasson -- 10:07 AM on January 31, 2011

As phenomenal as Intel's new Sandy Bridge processors have turned out
to be, nothing in this world is truly perfect. Intel announced earlier
this morning that it has discovered a flaw in the 6-series chipsets
that accompany the new processor family. While it reassures users that
they can "continue to use their systems with confidence," the
chipmaker has nonetheless halted chipset shipments until a new, bug-
free version of the silicon starts to ship out late next month.

What's the problem? Intel explains, "In some cases, the Serial-ATA
(SATA) ports within the chipsets may degrade over time, potentially
impacting the performance or functionality of SATA-linked devices such
as hard disk drives and DVD-drives." (..)"
