Hi FreeBSD Team,

I've got a AMD Athlon 700 Mhz Processor and I coludn't make a working
kernel. It works with the generic kernel, but when i compile a specific
kernel usinf 686 Class processor it gives me a Panic advice.
I'm usind 686 Class processor 'cause when using the generic kernel, in
startup, it detects an 686 Class processor, and also load some Pentium Pro
drivers.
Thanks every body,

Felipe Mesquita

If you get a panic, you should specify the details. Otherwise we
can't help you.

I'm pretty sure that we treat an Athlon as a 586.

These are things you can check on. Felipe did specify that it was
reported as a 686 class machine, and he's right. My machine:

CPU: AMD Athlon(tm) Processor (751.79-MHz 686-class CPU)

I suppose I could try building a kernel without i585 support, but I'm
not going that far to answer a question.

dmesg recognizes the Athlon as a 686 class CPU.

I have the following in my Athlon K7 custom kernel config:

machine i386
cpu I686_CPU

Works great, no panics, very stable.

Heh. Open mouth, insert foot.

I think I was thinking about Cyrix chips, but according to
/sys/i386/i386/identcpu.c, those get picked up as 486s, so I dunno what I
was thinking.

Sorry for the misinformation.

Eric

Don't think about those, no good will come of it.

Perhaps you were thinking about the AMD K6[-2].
