I try to add iomem=relaxed as kernel parameters. I tried adding it to /etc/dracut.conf.d/cmdline.conf as kernel\_cmdline=“iomem=relaxed” and than tried every combination of: dracut -force dracut --regenerate-all --force reinstall-kernel but the parameter will not work. Manually adding it at boot time works… What am i missing? ---

We manage kernel parameters via the bootloader. You should add them to `/etc/kernel/cmdline` or `/etc/default/grub` for systemd-boot and grub respectively. ---

Also for systemd-boot you will need to run `sudo reinstall-kernels` and for grub run `sudo grub-mkconfig /boot/grub/grub.cfg` after making the change. ---

Ah this, I have an alias doing the same thing, no need for this package : ```auto alias update-grub='sudo grub-mkconfig -o /boot/grub/grub.cfg' ``` At least Manjaro brings a bit more : > **[update-grub · master · Packages / Core / grub · GitLab](https://gitlab.manjaro.org/packages/core/grub/-/blob/master/update-grub)** > > GNU GRand Unified Bootloader (2)
