As far as we can tell the problem is 'using a VIA chipset'. The code itself is a fast copying loop using mmx/3dnow/amd athlon extended mmx stuff Pick up an Athlon documentation set (pdf on the web site) and you should be able to follow it. prefetch does what you'd expect, sfence is a store fence for non temporal stores (ie out of order stuff) amd movntq is an out of order move > FWIW - the RedHat 7.1 stock 2.4.2 athlon kernel boots successfully without oopsen. That doesn't have CONFIG_MK7k - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
