Are you sure about this? All those nifty specification updates for CPUs tell quite a different story. And yes IC producers usually have such things too, they just prefer to not publish them openly but rather decide to gag their customers (like OEMs) by non disclosure agreements, if those plan on getting a hold of those spec updates to work around the issues instead of throwing away all the chips they bought. But that just on a side note. Bad PCB design and bad quality components are usually the more common things causing problems. On the other hand, what was that story about the ICHs in quite some chipsets having problems with the SATA Ports? http://newsroom.intel.com/community/intel_newsroom/blog/2011/01/31/intel-identifies-chipset-design-error-implementing-solution BTW: Big OEMs decided to get those broken chips nevertheless for notebooks, because the problems usually do not occur with the first two ports and the chips will probably be VERY cheap *eg*. Marvell had issues (design) with the legacy PATA Interface on some PATA/SATA chips earlier, then bumped the rev. and fixed the silicon. Design errors and flaws are extremely common and there are certainly enough in any IC, question is, if you hit 'em and if they cause problems. And don't forget all the possible problems that arise from production flaws (bad wafers etc.). Anyway, concerning the original issue a bad PCB is probably rather the issue. And SIL is as good a choice as Marvell or JMicron in most cases.
