I'm not seeing that with my j6k.
But I'm building using "stable" gcc (gcc version 3.3.5 (Debian 1:3.3.5-13)).
I also have enabled SMP and DEBUG_SLAB in my kernel builds.
Diff between c3000_config and my mine is appended (It's short).
Kernel should warn about, but handle data alignment exceptions.
So this sounds like two bugs: one for the misaligned data and
another that the kernel isn't handling it properly.
I expect this is another exposure that gcc 3.x was hiding by
automatically aligning some data types.

Ok - those should be easy to sort out. I'll look at that tonight.
I haven't noticed it on my builds.
thanks,
