This isn't the latest firmware yet, it's the firmware we've been using
for a long time.

> iwm0: Could not empty Tx queues (error 35)

This is a driver-side issue which was recently introduced. The driver
treats this situation as an error while it is in fact a legitimate
situation that could be handled more gracefully.

I have a fix as part of a larger patch which isn't ready yet.
If this error bothers you I can commit my fix in isolation. But it's
really just a cosmetic issue since the driver recovers from it.
