Thanks for the suggestion.  Modinfo does produce that result.  But 
"the network doesn't work".  My environment is a VirtualBox VM of 
Centos 8 on top of Windows 10.  I've defined a bridged adaptor. The 
hardware is the Broadcom adaptor, using DHCP.  No firewall is running 
in Centos 8 yet.  This exact configuration works fine with Centos 7.

The symptom I see is that DHCP, Ping, DNS Lookup all work, but no 
data transfer seems to work.  I tried a CURL command to a local web 
machine (works with Centos 7), and it just hangs.  The web server 
does not see the request.

When I switch the network adaptor (in the VM) to NAT, everything 
works, probably indicating that the selection of the adaptor is the 
problem.  I used the NAT interface to complete the install.  Do you 
have any ideas?


***********  WHOA ***************

It appears that this is not a Centos issue.  My other VM's have 
stopped working also.  The common factor is the use of a Bridged 
Network in VirtualBox on Windows 10 updated last week.  Based upon 
prior similar events, I'd guess it's a Windows screw-up.  Oh well.
