Sorry I didn't follow up on this. Things looked better after the patch
but I was seeing a strange issue where the memory was being reduced to
some minimum and the balloon
I've been trying to use the Hyper-V balloon driver to allow the host to
reclaim unused memory but have been hitting issues. With a Hyper-V 2012
R2 guest with 4GBytes of RAM, dynamic memory on, 1GByte minimum 10GByte
maximum, 8 vcpus, running a 3.18.0-rc3 kernel with no swap configured

These patches (on top of the "Drivers: hv: vmbus: Eliminate calls to

framebuffer driver would fail when booting a 3.17.0-rc2 verification
kernel on a UP

This patch set resolves a number of BUG_ON crashes I was hitting on
Hyper-V while booting a kernel with verification options on. With these
I can complete a 3.17.0-rc2 boot on an SMP setup although patches from

While booting a Hyper-V 3.17.0-rc1 guest on a 2012 R2 host a BUG was
triggered while registering hyperv_fb which in turn caused a panic.
Various kernel debugging options (CONFIG_DEBUG_PAGEALLOC,
CONFIG_SLUB_DEBUG=y...) were on at the time. This only seems to happen
if the guest is being booted with

Now we get to the issue I've been meaning to report: changing the MTU of
a Hyper-V network interface while traffic is flowing through it triggers
a BUG. I've seen this happen on a variety of kernels but the trace below
is from 3.17.0-rc1.
Steps to reproduce:

While booting a Hyper-V 3.17.0-rc1 guest on a 2012 R2 host a BUG was
triggered in drivers/hv/channel.c:504 which in turn caused a panic:

After a variety of issues on Hyper-V (host is running Windows 2012 R2) I
updated to the latest kernel (3.17-rc1
7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9), turned on a bunch of kernel
validation options and booted which has resulted in a BUG being
triggered (IP claims to be at netvsc_select_queue),
while they implement post SPC-2 features.

With the 3.14 kernel Hyper-V no longer reliably enables its networking
devices in time on cloud images leading to network devices permanently
remaining offline.
