I'm continuing to test without the throttle. I'm @ a loss for why it tracks some systems and not others.
There doesn't seem to be a reliable way to drop the number of tags since the system may not always come up. I don't think there's an option in the kernel to do so.
Just add a call to camcontrol early in the rc process, prior to fsck starting up. camcontrol is on the root filesystem. You can also modify the ahd driver to tell cam that it can only handle 32 commands per-target.
I offer this patch to make a loader tunable out of the maximum tags supported.
