Hi, We are observing a reproducible kernel Oops with the firewire_ohci driver on a Hewlett-Packard HP Z800 Workstation running 32Bit OpenSuSE 13.1. Are the following exceprs from kernel logs of any use to you? Do you need further information? Yours, --martin May 30 17:10:43 rt-z05s3 kernel: [ 309.697867] firewire_ohci 0000:37:09.0: failed to read phy reg 4 May 30 17:10:43 rt-z05s3 kernel: [ 309.697870] CPU: 5 PID: 2690 Comm: systemd-udevd
