That looks very similar to a problem I had with an early 2.6 kernel on a
Dell 1RU server -- there was some sort of odd hardware problem between
the motherboard and the kernel, and a later kernel update cleared the
problem.
This was a number of years ago, and iostat showed a lot of I/O going on
when it wasn't really expected on that machine, but fixing it really was
more of a "might as well try the latest kernel" type of thing, nothing
direct was ever found.
