I've been looking at this bug for a while now, it crops up when I cross
compile a 64-bit kernel with a newer gcc. Randolph was saying that cross
compilng with 3.0.4 doesn't generate this problem. If I remember right
it's trying to free a shared memory inode that is still being used, and
that scenario shouldn't exist. Why this happens is a mystery. 

I see this twice, once for ssh, and something else generates the error.
It appears non-fatal, and I want to blame the compiler :)
