Subject: 2.6.27-rc7 no init found on the root partition?

Hello,

I have a box that has XFS root partition, I have kernel 2.6.26.3 that boots
pretty well on that box. Today, I've tried 2.6.27-rc7 (so that I can test
NFSv4 over IPv6), but the kernel is unable to boot. It says that root
partition is mounted, XFS file system but no init found.

If I pass init=/bin/bash, it complains that /bin/bash not found, trying fall
back to init and no init found at all. If I change root from /dev/sda1 to
/dev/sdb1, it complains that root file system not found and I have
possibilities: /dev/sda1, /dev/sda2, /dev/sda3, /dev/sda4.

The same kernel (not the same binary) boots ok on similar box but with ext3
root file system.

The kernel config was made from 2.6.26.3 (that works pretty well) with make
oldconfig.

Any clues?

The broken config is attached, am I something missing or is there a bug in
2.6.27-rc7 related to XFS root?
