After encountering this problem I updated my firmware from phase 7 to phase
11 but this did not fix things.

My question is: "Is the LSI driver even in 8-STABLE yet?".

If not I'll upgrade to 9-STABLE to get the new driver.

If it is, then I want to downgrade to just before it came in to see if this
high interrupt rate problem is fixed.
