All, new serious bug discovered in Pentium-MMX chips: news.com The bug is that a regular user instruction but with incorrect argument causes total lock-up of Pentuim MMX computers instead of generating an interrupt to operating system to handle it. All P5-based multiuser servers are affected. Some opinions from Usenet people: "What makes me think I'll run into this is that the instruction is not privilaged and I have a Linux box with a lot of users. Any one of them could now crash my system at will without even having to try hard, and there's nothing I can do but disable telnets until I can get a different chip. I'm sure the Solaris x86 box at my university will be going down a lot... Bad news for the people who have CS projects due. I'm sure the people running NT won't be happy either."-Steven Brown "For the U*ix systems out there running under Intel CPU's, this is NOT just stirring the pot!!! Any malicious user can now bring down the entire system at will, with a good chance of getting away with it!!! This blows BIG TIME! I'm glad most of my CPUs aren't Pentiums!" -- Peter F Curran "I'm sitting on a multiuser system, running an Intel Pentium CPU, this bug is like a few miles worse than the FDIV bug ever was. So, while I might not have bothered exchanging my CPU during the FDIV bug era, I surely would now, although I severely doubt Intel would ever agree on doing that... The FDIV bug was a laughing matter. A big company with a monopoly being forced to replace their product. This one bothers me." -- Joel Lindholm Good job Intel, again.
