Comment 15 for bug 1766377

      Just to make sure you got the latest, the 4.17.x kernel did not work well
enoguh to leave it running, it broke kernel-nfs-server among other things.

      I am pressenting running 4.15.0-21 and with this kernel I would still
get these hangs except that I discovered disabling certain hardware offload
functions stops it, so presently in my /etc/rc.local file on the affected
servers I have: /sbin/ethtool -K eno1 gso off gro off tso off

      With this in place no hangs, slight performance penalty but no hangs.
