BeagleBone Black - 3.8.13-bone21.1 - strange timestamp in dprintk

[susisstrolch]

Tried to run my DVB Sky USB-Module with BBB and self compiled kernel.
BBB hangs on heavily used USB (like this device) and shows back jumps
in dprintk timestamps:
Jun 20 17:33:19 arm kernel: [ 802.654332] dvbsky_usb: dvbsky_stream_ctrl() -off
Jun 20 17:33:19 arm kernel: [ 803.375415] dvbsky_usb: dvbsky_stream_ctrl() -off

I wonder if it works on 3.8.13 with x86? The musb bus is still a little fragile with our v3.8.x based kernel..

Little searching found this patch:

Thats exactly the Patch I use. Btw this One Works absolute stable in RPi 3.8.13 and 3.9.7.
it looks like some internal data gets overwritten on heavy USB usage.
