I have to wait for several minutes...) A quick tip: inline patches tend to be better than attachments on LKML. This is because if the mimetype of the attachment is something like octet/stream then various tools (e.g. https://lkml.org/lkml/2014/8/26/271 and https://patchwork.kernel.org/project/LKML/list/?submitter=100981 ) won't archive/extract the patch... I rebased your patch on top of the K.Y.'s "Drivers: hv: vmbus: Eliminate calls to BUG_ON()" patch set (see below). The combination no longer triggers the bug and it doesn't take too long to boot but the network interface fails to work (which I believe is .
