I'll throw in my two cents on this...
Running Intel Pentium 120 and 133 chips on the same boards worked fine.
I bought two Asus T2P4 boards and two K6-200's. The K6's were
backordered, and so I ran an Intel Pentium 120 and 133 in the boards. No
problems with "make world". Once the K6's were installed, I started
having the same problems everyone else here has: 'as' getting corrupt
input and dying, gcc internal errors, sig 11's, sig 6's.... you name it.
One of the machines also had Windows 95 on it, and I noticed many more
GPFs than even usual... Even DOS-extender programs, like MAME, started to
misbehave and crash. I decided pretty quickly that it didn't have
anything to do with FreeBSD...
I had my vendor get me a third MB/CPU, this time as a PRETESTED set from
his vendor. Much to my surprise, the thing worked. Even more to my
surprise was that there wasn't any heat sink paste on it, and I'd also
forgotten to plug the CPU fan in. Yet it had survived half a dozen make
worlds. Weird...
I started swapping chips and fans around, and found at first that the
first two chips would run great in the new board, but after a few swaps
even the known good chip started to fail, even after everything was
restored exactly the way it had been on the pretest set. Argh.
By the time I'd gotten done doing all this, Intel had dropped their
prices... so I (very grudgingly!) returned the pretest set and the other
two K6's, and got a pair of P200-MMX's. Even overclocked to 225mhz
(3x75), they've passed every torture test I can throw at it, including
many dozens of "make world"s.
