I've never seen anything like that, although I don't have anything  
hooked up to any mesh here right now. If the mesh problem would be - 
current only I'd blame bus_space-ification fallout but with 4.0 the  
only significant change I remember was to fix synchronous data  
transfers ages ago ( IIRC they're still not enabled by default ),  
before that mesh hasn't been touched for years. Do older kernels work?

That sounds plausible.
