What counter-measures > are taken within FreeBSD community? I voiced similar concerns on a tech forum back when the C2Ds were released, going purely off of the Errata. As it turned out, most of the entries I had concerns about were either 1) addressed by future processor steppings, 2) microcode updates, or 3) were not causing issues in present-day operating systems. The bottom line is that every processor - Intel, AMD, VIA (god forbid), Transmeta, Cyrix (back in the day), blah blah blah - has bugs. The manus know this when they come out, which is why most of them provide errata. This isn't to say Theo has a point (he does), but he's borderline rabid when it comes to stuff like this. It's just how he is as a person. As long as you're aware of his personality type, it's then easy to conclude that he's focusing on the right stuff, but over-dramatising it. That said, two of our production servers use C2Ds (one 6600, one 6420) and neither of them have any issues (especially the one using the 6420, which is a heavily-loaded MySQL box) using RELENG_6. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
