I tried forcing tsc on my 4801, and it seemed to boot slower, but it didnt hang. Also, you have a running kernel (or you wouldnt have gotten the /proc/cpuinfo) can you modprobe scx200_hrt on it, see if it loads (iirc, it expects a particular PCIID, and your SOC may not match - or it might) if old kernel has it, try booting new one (via pxe) with clocksource=scx200_hrt what is an MP-6x10 board anyway ? bios version is 0.99h (newest), and it supports some kind of MFGPT workaround, which I have also been trying switching on.
