[Bug 1497636] [NEW] Network disconnects sporadically

 

Public bug reported:

I installed Ubuntu 15.10 in VMware Workstation 12 Player to give it a
try and I noticed that the network disconnects and reconnects every
several minutes. I can't see this in other virtual machines or in the
host machine (which runs Ubuntu 14.04 LTS). Here is a part of the
syslog:
