Paul, <Re: Pentium Bug .. A good analogy is ..at 65 MPH .. slamming your automatic transmission into PARK - a totally doable deed> You pretend to be smart but your analogy is wrong.
The correct analogy would be driving a bus at 65mph, full of people, and ANYONE from the street can slam YOUR transmission into PARK, and laugh at how you all crash...

In a good device an attempt to do this "from the street" just causes an interrupt and MAKES IMPOSSIBLE to crash a computer "bus". Your friends at Intel are all wet again with their validation department as with Dan-411 and FDIV bugs. I hope they will reinvest more money into R&D/validation (at shareholder's expence, of course).

I agree with you about Collins, what he has done is irresponsible. Every would-be hacker who reads that article will want to try it out.
His motives are obvious, unfortunately he has a little more to work with this time than the last "bug".

I disagree with your analogy. If I spilled a cup of coffee on top of my CPU, I would not expect it to work, that is beyond the control of the processor. However, an invalid instruction should generate an interrupt, and not lockup the CPU. Period.

If this instruction is accessible from user mode, it is a potentially serious bug, because operating systems like NT rely on this mechanism to remain stable, and because of guys like Robert Collins. IMO Intel needs to respond with a fix.

While Collins may be a slick and pompous opportunist who deserves corporal punishment, and that bug may not affect Joe Average's desktop, the bug DOES threaten one of Intel's cash cows --namely the highly lucrative server market. In fact, I am heartened to find that I'm able to login to SI at all, given that it runs on Pent/Pro servers and people like Collins may have a vested interest to hack and crash a site as popular as this --more headlines!
