When the issue happens (it looks due to the layout of the struct somehow...),
can you try the small workaround patch at
https://patchwork.ozlabs.org/patch/518469/?
I paste it below:
diff --git a/include/linux/netdevice.h b/include/linux/netdevice.h

@timg-tpi
I reverted it on latest ubuntu-vivid, but there is variable dependency
with the other related commits, so I patched like below
it is better, but still dropping is there.
original 100 -> 0.3
below patch 100 -> 15~20
Thanks.
Seyeong - can you try reverting 'hv_netvsc: Implement partial copy into
send buffer' ? This backport was dropped from Utopic because it caused
regressions. Perhaps the same is true of Vivid.

I built a Vivid test kernel with a cherry pick of commit 0d158852a. The
test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1521053/
Can you test this kernel and see if it resolves this bug? If it does,
we can submit an SRU request for that commit.
Thanks in advance!
Hello Joseph
I tested your test kernel, and confirmed it's working fine.
Thanks
