[CentOS] Strange Network Bug Locks Up CentOS 7 Laptop

All,

I have a user who has a Dell Precision 7520 laptop, and we're running CentOS 7, latest kernel.
This morning he had two lockup incidents. Nothing in /var/log/messages stands out so far,
but did get this information when running 'abrt-cli list --since 1560891312':

Has anyone seen this behavior before or this message? Seems like something related to network scheduling (?) or something.
Any feedback would be appreciated. Thanks.
