SubjectX fails to start with latest Linus git

Hi Ingo,

Starting X (autostarted with GDM) manages to lock up my system
(requiring a hard reset) after the first few tree merges of the window,
and bisection shows:

-----------------
19ef9309273d26cb005cb23e6a370353dca91099 is first bad commit
commit 19ef9309273d26cb005cb23e6a370353dca91099
Author: Ingo Molnar <mingo@elte.hu>
Date: Fri Jan 25 21:08:34 2008 +0100

printk: use ktime_get()

printk timestamps: use ktime_get().

Some platforms have a functioning clocksource function only after
they are done with early bootup, so delay this until out of
SYSTEM_BOOTING state.

it's also inherently safe now, as any bugs in this area will be
caught by the printk recursion checks.

-----------------
as the first bad commit. I have no idea why that would cause problems,
so it could also be some timing-related problem that just happened to
bisect to this patch.

I will try advancing to the head of Linus' tree and then reverting this
patch to make sure it fixes the problem, but I figured I'd send this
first to see if it is obvious to anyone.
