I reverting both, but it doesn't fix the problem.

Another finding is that the boot reaches to the exec of init, at
least.  So I could get a sane state with init=/bin/sh.  The message
appears after the init script running udevd.

Also, the machine could boot fine with the recent linux-next kernel,
at least, 20080711-0714.  (It failed for last couple of days, but it
can be irrelevant.)

I'll investigate a bit.  Any hints are appreciated.
