Post #2655227

Not the same distro, but on my system, the relevant file is located at `/etc/default/grub`. Find the line that says `GRUB_CMDLINE_LINUX`, uncomment it if necessary, and add your kernel parameter to it (mine has `GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax"`, for historical reasons). Then run `grub-mkconfig` with appropriate arguments to regenerate your grub configuration.
