Hello!
Same problem here.
I installed the update, rebooted the machine, and started experiencing issues.
The system works fine until I start a Virtual Machine. When I start my Windows Guest, after a few minutes, the host system becomes unstable. The network connection stops working, some processes cannot be terminated, and the sudo command gets stuck. Power Off and Reboot do not work, and I have to perform a hard shutdown.
I checked dmesg and syslogand noticed messages like the following:
----

From my side I had to uninstall version 17.6.0 and installed again the previous one 17.5.2.
I hope VMware Broadcom will fix it soon.
