2.6.35 is perfectly fine on x86, so I suspect that it is something
ARM specific. Most likely it is related to the VIVT platform support
changes, but you really need to bisect so we know exactly waht
change has broken such basic functionality on your platform.

Note that the bug may not even be in XFS, so you really need to do a
full bisect, not just of the changes in xfs in that time...

Cheers,

Dave.
