Sorry, to me it sounded a bit like you had an idea for a fix and were
going to give it a try -- similar to how the maintainers for a r8169
driver and the igc driver provided fixes for bugs recent LED changes
exposed.

But sure, you are right, in the end some LED change seems to have cause
this, so the duty to fix it lies in that field. Therefore:

Lee, what's the status here to get this fixed before the final?

Ciao, Thorsten
