kernel nfsd error

[Skunk Worx]

We've been running tests using our "ion" driver and card. That's where 
the "ion" module comes from.

Things have been going well, expect today this came up. It's been a few 
days of NFS mounts/umounts on and off, then this.

Not sure how much good it does posting the text when our module is 
inserted into the kernel.
