Description of problem: The Hyper-V framebuffer module isn't loaded while we are still in the RAM disk which means text mode is used. Version-Release number of selected component (if applicable): dracut-038-32.git20141216.fc21.x86_64 How reproducible: Reproducible every time. Steps to Reproduce: 1. Install Fedora 21 on Hyper-V. 2. After choosing the kernel at the grub prompt watch the boot up screen. Actual results: Pretty graphic of the Fedora emblem filling with white. Expected results: Text bar goes across the bottom and at some stage the screen is resized leave the old black screen at the top left and grey in the newly expanded area. When shutting down this messy screen is kinda of shown but with the emblem overlayed too. Additional info: This occurs because the Hyper-V framebuffer driver isn't part of initramfs. It is not picked up with most other drivers because it doesn't seem to use drm_crtc_init like other drivers. Adding instmods hyperv_fb to modules.d/50drm/module-setup.sh (as shown on http://paste.fedoraproject.org/184642/43121142/ ) makes resizes the screen early (preventing later mess) and makes the pretty splash occur.
CC'ing Hyper-V folks.
