Public bug reported:

After installing a fresh daily image on a generation 2 Hyper-V VM, the
following two lines appear during start and in the system log:

[   19.773125] hyperv_fb: Unable to find PCI Hyper-V video
[   19.773125] hyperv_fb: No memory for framebuffer

The modules does not work, as the display resolution is not set
correctly. In a generation 1 VM the Problem does not exist.
