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.
