Hi Michel, Thank you very much for the insight on CONFIG_IO_STRICT_DEVMEM. I was able to use SystemTap to find where the error was occurring in the kernel. It turns out the vesafb takes the framebuffer and sets it IO_RESOURCE_BUSY using sysfb. When the framebuffer memory is set as busy and the strict devmem is enabled it will not allow the userspace to mmap this area. I changed my grub config to use GRUB_TERMINAL=console and that fixed the problem!!
