Problem is, it's the storage configuration (at administration time, not
kernel build time) that matters, too.

I have XFS on Fedora with 4k stacks on SATA /dev/sdb1 on my x86 mythbox,
and it's perfectly fine.  But that's a nice, simple setup.  If I stacked
more things over/under it, I'd be more likely to have trouble.
