Hi, it's timing related.

I just tried booting with an initrd, and i want to capture the full error 
message, but with initrd, the problem went away.

The only difference between the two config is:


Right now, I can reproduce this problem only when I
running 2.6.32.2 with a specific kernel config.

If I attach a serial console or use initrd to capture
the fail boot log, the problem disapeared. Even running
2.6.31.1 with the exactly same config, no problem. 

So I will say that it's very hard to reproduce this, it's very
subtly timing related. 

I remember when running 2.6.32-rc8 and 2.6.32, the same
problem happened twice, I just can't reproduce it.
And with 2.6.31.x, never running into this.

Oh well.
