From 43dc24f369543dccf99b6545a3b4e9312ff042a9 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.
