Thank you. Tested on 4.4.0-131-generic from xenial-proposed. I can

[Bug 1780761] Re: kernel 4.4.0-130-generic - packet loss with ip forward

2018-07-17 Thread Joseph Salisbury
This bug may be fixed by the following commit, which is in Xenial -proposed:
758c626 xen-netfront: Fix mismatched rtnl_unlock

Would it be possible for you to test the proposed kernel and post back if it 
resolves this bug?
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to 
enable and use -proposed. 

Thank you in advance!
