That's not the same problem as you.  The INFO text doesn't tell you the
source of the problem, the included thread information does.  To debug
that you need to be an XFS developer.  Which is why you should report
that to the xfs list, not here.

Ahh, I didn't recognize your name.  You're the guy trying to build the 8
drive storage appliance with a 36 core Tilera chip.

What is the latest Tilera supported kernel?  Do they support any 3.x
series kernels?  How often do they update their kernel and userland code
so you can get badly needed bug fixes?

This is the 2nd glaring reason demonstrating you should have gone with
x86, or another fully supported low core count low power CPU (MIPS), as
I previously mentioned.
