Just 3 ideas to try:
1-Try noplymouth on cmdline if plymouth is installed, or uninstall it.
2-replace grub2 with grub legacy if not using UEFI, leave quiet off cmdline,
and set video mode using either vga= and/or video=.
3-ask on intel-gfx@lists.freedesktop.org mailing list and/or search its archive.
