syslog events around bluetooth log up

I have not yet chased down the KDE bug I mentioned.  However I think it is
unrelated, for the last several days I have been testing with a new (clean)
user account which bluetooth always starts powered up after a resume, and I am
still seeing the bluetooth lockup bug.

I'm attaching a system log dump from system resume this morning.  Here are some
highlights:

Dec 12 07:28:19 myhostname kernel: usb 2-6:1.0: rebind failed: -517
Dec 12 07:28:19 myhostname kernel: usb 2-6:1.1: rebind failed: -517

I'm not sure what this means, but usb 2-6 is my 7260 bluetooth device.


At 07:28:41 my networking is up, VPN connected, and bluetooth mouse turned on
and working.

A few minutes later (07:33:02) the BT controller gets reset without any user
intervention that I am aware of, I was just clearing emails.  After this, you
can see at 07:33:21 the USB disconnect, which is a direct result from me
issuing a "rfkill block" / "rfkill unblock" to manually toggle the device.
