But, newer Linux kernels forbid access to that region. In recent Linux kernels, there is a module for that. `sudo modprobe memconsole_coreboot` should load it, and then the logs should be available under `/sys/firmware/log`. If you don’t have that, please pass the parameter `iomem=relaxed` to the Linux kernel. For example, by pressing `e` in the GRUB menu. […] Thanks, Paul
