This tells me you're not being mistaken for HT.

It also suggests it's the policy not doing what you want it to. If your
interrupt rate isn't high (according to what metric I have no idea;
presumably it should depend on the expense of handling it, which is
driver-dependent but about which the code has no knowledge), it won't
rebalance the irq's.

If you actually manage to get interrupt rates exceeding its thresholds,
you should see interrupts migrated, but only dynamically and on-demand,
not under light usage.

There might still be something wrong with it, but we'd have to dig deeper.
