Intel has issued a press release stating that they will be recalling "Cougar Point" (That's the codename for 6-series chipsets, as found on Sandy Bridge motherboards) chips due to an issue with the onboard SATA controller, it appears that it "degrades over time" causing poor I/O performance in the longer term.
Those of you with H67/P67 'boards need not worry - it's perfectly safe to go about your day to day computing - just be on the look out for recall notices.
Intel are expecting a $300m hit to their revenue for the first quarter as a result.
Fixed chipsets should roll out in April, giving AMD ample time to launch it's own Bulldozer line of CPU's and enjoy some domination.
This is all vaguely reminscent of Intel's problems way back in 2004, with the 915 and 925 chips' PCI-e controllers.
