Please try to deactivate everything related to framebuffer and specific video hardware in your kernel config. See if it helps, then activate one option at a time until it breaks again. Specifically: CONFIG_FB=y CONFIG_FB_BOOT_VESA_SUPPORT=y CONFIG_FB_CFB_FILLRECT=y CONFIG_FB_CFB_COPYAREA=y CONFIG_FB_CFB_IMAGEBLIT=y CONFIG_FB_MODE_HELPERS=y CONFIG_FB_TILEBLITTING=y CONFIG_FB_VESA=y CONFIG_FRAMEBUFFER_CONSOLE=y The only thing you really need for the start is CONFIG_VGA_CONSOLE. Hope this helps, Florian Philipp P.S.: Please don't top-post in the future. Use an email client that allows you to write your response below the text you quote. That makes large threads easier to read.
