Markus Heinz, the next step is to fully commit bisect from kernel 3.13.0-71 to 3.13.0-73 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your understanding.

When running "goobox" (a cd-player application) the application hangs for about 30 seconds before being initialized. During this one core of the cpu is running at 100% utilization. The following lines appear then in the syslog: Dec 24 13:14:27 computer4 kernel: [ 1386.238349] usb 3-1: reset high-speed USB device number 2 using xhci_hcd Dec 24 13:14:27 computer4 kernel: [ 1386.293951] xhci_hcd 0000:03:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff880036272600 Dec 24 13:14:27 computer4 kernel: [ 1386.293955] xhci_hcd 0000:03:00.0: xHCI xhci_drop_endpoint called with disabled ep ffff880036272640 The CD drive is a external USB one connected to a USB 3.0 port: Bus 003 Device 002: ID 0e8d:1806 MediaTek Inc. Samsung SE-208AB Slim Portable DVD Writer This behaviour appeared with the kernel version 3.13.0-73-generic #116-Ubuntu. Running "goobox" on the same system with kernel 3.13.0-71 does not exhibit this behaviour. Using the newest available kernel 3.13.0-74 the problem persists. Kernel, goobox and the other software are installed from official Ubuntu packages.
