I've been using AMD processors almost exclusively in my main work machines for over 4 years, and I've been very happy with them. I'm currently running a K6/233, a K6/333, an Athlon 750, a Duron 850 and an Athlon XP 1700. Last August, though, I bought a machine which gave me a lot of trouble, the Duron 850 mentioned above. I found that it would freeze for no apparent reason. I established that it wasn't the memory by taking the memory of another machine and running it like that; it made no difference. I ended up also changing the motherboard and the processor, but the hangs continued. I could expect a hang within 8 hours when doing 'make release'
Just for the fun of it, I tried running Linux on it. I've been running a kernel build and 'make clean' on it now for 36 hours, and it's still running fine. Yesterday some Linux friends of mine came around and looked at it and told me that the Linux kernel I was running on the machine (2.4.16) had had a number of AMD-specific fixes put in. He didn't go into more detail, unfortunately, but I'll ask him again when I have time: it could be something relating to chipset bugs we have seen and fixed. It would help to know, though, if other people are experiencing similar problems. Please let me know if you're having problems with AMD processors which seem to be specific to FreeBSD, especially if they're hangs (i.e. the machine stops reacting, but the display still shows the last state, it doesn't reboot or panic). Information that could be interesting is (here my values): Processor: AMD Duron 850 Motherboard: ECS K7VZA Memory: 1 128 MB SIMM, 100 MHz.
