From fd32d8e0491164b873a1ceb1d3860be8ef45f888 Mon Sep 17 00:00:00 2001 From: Julian Andres Klode Date: Fri, 19 Jun 2020 12:57:19 +0200 Subject: [PATCH] Pass dis_ucode_ldr to kernel for recovery mode In case of a botched microcode update, this allows people to easily roll back. It will of course break in the more unlikely event that you are missing a microcode update in your firmware that is needed to boot the system, but editing the entry to remove an option is easier than having to figure out the option and add it.
