With kernel 2.6.26 and older I used successfully the following mount options in my fstab:
/dev/sda2 / xfs defaults,noatime,nodiratime,logbufs=8,nobarrier 0 1

But with 2.6.27 the root-partition is mounted read only, although mount and cat /proc/mounts shows rw! E.g. I can create a directory, but can't do a chmod on it. And on boot many commands fail.

But I discovered a workaround. You have to remove all mount options except for defaults.
Nevertheless it seems to be a kernel or xfs bug.

Steps to reproduce:
use kernel 2.6.27 mount an xfs root partition with the options named above.

workaround:
remove all options except for defaults
