Re: [GOLDMINE!!!] Athlon optimisation bug (was Re: Duron kernel

[J.Brown]

I don't have any problems with the kernel, but if I'm compiling (say) the
kernel or any large program, user-mode apps like gcc, make, etc all
randomly segfault on me.

I'm running a Duron 800 on a Asus A7V133 mobo - and no bios version I've
tried has made a bit of difference yet :p
