[Bug 578944] [NEW] Hyper-v Screen Drawing is Slow

[Aleks Rudzitis]

Public bug reported:

When installing Ubuntu 10.04 in Hyper-V, the text drawing speed (sorry,
I don't know the proper name for it), is incredibly slow. I imagine this
has something to do with how the linux kernel interacts with the
framebuffer provided by Hyper-V. It can take something like 2 to fill an
entire screen with text.

Installing integration components makes no difference (since this is a
text-only server install anyway).

This bug DOES NOT exist in the mainline kernel.
