2.2.16 Alpha: "Fix SMP rescheduling with lock held"

Subject: 2.2.16 Alpha: "Fix SMP rescheduling with lock held"

I have a bunch of DS20Es running 2.2.14-6.0smp (the kernel compiled by
RedHat for RH 6.2), and they have several spinlock stuck messages while
booting, and more systematically happen when doing certain things (loading a
particular module). What's more annoying is that the machines occasionally
freeze under heavy load, and when they do, they're periodically printing a
spinlock message on their console.

Does this 2.2.16 patch perhaps fix this or does it go deeper? When Alpha SMP
was first developed it was stress tested on an ES40 by Jay and friends; do
all 2.2 kernel releases get similar testing these days? It's hard to believe
that 2.2.14-6.0smp would pass that test.
