I've identified another possible bug in the Hyper-V drivers: When the
Hyper-V Synthetic Video Frame Buffer Driver is built into the kernel,
and the VM is paused and continued, the top two lines of the console may
become distorted. See the image at http://imgur.com/kIExFP3.

Can someone look into it?

Just to clarify, I can confirm this bug under both the patched Gentoo 3.10.32 kernel and the vanilla 3.13.5 kernel (see the image at http://imgur.com/mYUTzgt). Is the framebuffer somehow getting corrupted?
