I've only recently started using xfs, so I couldn't say if its new
behaviour. I did notice that it took a week or so for problems to set
in; my theory is that as the filesystem got a bit aged, its
datastructures got a bit more complex, and cause the kernel code to use
more stack. But that's just a guess.
