I do see that the driver can be loaded without a drop in

it is only activating the driver that triggers it. Another thing I see
is that deactivating it doesn't fix the problem. In that I can go from
run level 5 to run level 1, where networking is shut down in the
process, but the performance in run level 1 will still be slow.
Another potential clue maybe that I didn't see such a drop with raid0
performance when I started using the sky2 driver. So I suspect it is
just an interaction between the raid5 code and the sky2 code.
Just before leaving home last week I noticed that sky2 was causing an
interrupt storm on my new toy, which explained the massive performance
problems I saw there. Since I'd just taken the sky2.[ch] from the netdev
git tree and compiled them against the Fedora kernel I didn't report it;
just intended to look into it further when I got home.
