Hello,
With 3.6.0-rc6 I see a lot of these lines:
[ 216.240493] ehci_hcd 0000:00:10.4: Waited too long for the async
schedule status, giving up
So about 2 in a second.
Can you provide a usbmon trace for that bus? Instructions are in
Documentation/usb/usbmon.txt. Also, it would help to see the contents
of /sys/kernel/debug/usb/devices.

There is a DVB-C USB Device (Technotrend TT-connect CT-3650) plugged in.
I don't have any problem with it, can watch TV or recording with it.
When I remove that device, no more complaining.
What's wrong with my setup? Maybe my .config might be a little bit
strange, I use this machine mainly for testing (and streaming DVB-C)
Probably nothing is wrong with your setup; most likely the problem is
in your EHCI hardware. What does "lspci -v" show?
