It's not obvious (to me) whether this is a driver bug, a hardware bug,
expected-normal-behaviour or what - those diagnostics (which we get to
see distressingly frequently) are pretty obscure.
That great spew of "set_level status: 0" is fairly annoying and useless.
Quite a lot has changed since 2.6.20. Are you able to test, say,
2.6.22-rc5?
