ALL multiuser Unix systems running on Intel Pentium (including MMX) processors are vulnerable to the 'F0' bug. Any user can bring down the entire multiuser system by typing a few lines on his terminal.

To say this is not a bug is to say the sun revolves around the earth -- true only from an Intel-centric point of view. The whole idea of having a "user mode" in a CPU is so that the operating system can maintain control at all times. If a new CPU came out with an instruction set that allowed a HALT instruction in user mode, NOONE would buy it, it is a totally useless CPU. The F0 0F C7 C8 opcode is a halt intruction which Intel forgot to document in their specification.

How long do you suppose AMD can go on losing millions quarter after quarter??

With a net worth over 2 BILLION dollars, quite a while yet. Save yourself some aggravation and sell Intel now. You can get it back in the sixties.
