HQF Shaper Backg + Dot11 driver = 50%+ proc time ... at iddle

I have a router in iddle mode; ie: all interfaces are shutdown, and even then I am seeing high CPU loading

I am not using HQF at all, I just learned what it is seeing the following cpu output.

I want to use the radios but even while they were shutdown for the last 30 minutes I see the driver eating 20% cpu time ... steady.

This problem became apparent while working on the console; very unresponsive, eg: I hold a key and I see huge delays.

Cisco CP takes eons to complete the discovery process of just this router entered by IP.

show processes cpu sorted 5min:

CPU utilization for five seconds: 88%/0%; one minute: 84%; five minutes: 57%

... question are obvious:

what the hell is HQF doing here when I not configured anything associated with it ?

why am I seeing a 20% steady load on the dot11 driver if the interfaces are shutdown ?

Re: HQF Shaper Backg + Dot11 driver = 50%+ proc time ... at iddl

I'm starting to figure out what is happening; just found the following:

QoS is disabled by default; however, the radio interface always honors tagged 802.1P packets even when you have not configured a QoS policy.

Which explains why I am having those processes running but I am not able to figure out why they take 50% CPU load.

How can I completely disable said QoS on a radio interface ?
