Lukas,
There was one particular kernel change introduced in 3.10.0-1062.18.1 that has triggered a given set of crashes. It's possible, though, that there is a lingering problem affecting older levels of 3.10.0-1062. I believe that crashes occurring on older kernels should be treated as separate problems.

And are you sure it is present only in -1062.18.1.el7 kernel? I think it is
present in all -1062.* kernels..
