Lightning talk from CentOS Dojo at DevConf.us
summary
A weird boot splash appears on Super Micro X10/X11 after updating to CentOS/RHEL 7.5 and does not occur on 7.3 or with mainline kernels; the issue affects only the early splash framebuffer (system boots fine once the OS loads) and shows a legacy-mode VGA look. The problem reproduces when using the vendor kernel from the L repo, prompting questions of framebuffer/VGA swapping and whether the fault lies in the kernel, Supermicro firmware, or a config workaround (PXE/WDS/PXE configs available on GitHub).
