Re: [gentoo-server] strange bogomips difference

The difference between the processors is normal as far as I can tell.  I have
two MP2800+ processors and they are detected differently even though they are
definitely the same model.  (Consecutive serials)  I haven't had any stability
issues other than a BIOS bug.  What motherboard do you have?
