I thought after sending the last msg, that I would look at the 
i386_defconfig to see if I could get a clue about this TSC clock its 
mewling about.

It doesn't even exist in either defconfig. ?????

This is 3.12.9 ATM, 3.12.6 will also boot, but I am going to pull that 
defconfig and see it it will still boot. Just for S&G of course.
