I have been trying to upgrade to Leap, the new version of openSuse that 
contains the version 4 kernels. But I get an internal error message 
stating that there is "unknown udev device 
/dev/disk/by-id/wwnQx5002538844584d30-part2" I filed a bug report last 
week, but no action has been taken yet. openSuse Leap does not appear to 
like Samsung SSDs:-) My 13.2 system (current) has been running on them 
for a year.
