[Madaidans-insecurities page](https://madaidans-insecurities.github.io/guides/linux-hardening.html#kernel) describes each of their function and how they improve security of the system so lets add them to `/etc/kernel-hooks/secureboot.conf`: ``` -cmdline="... slab_nomerge init_on_alloc=1 init_on_free=1 page_alloc.shuffle=1 pti=on randomize_kstack_offset=on vsyscall=none debugfs=off module.sig_enforce=1 lockdown=confidentiality mce=0 loglevel=0 iommu=force spectre_v2=on spec_store_bypass_disable=on tsx=off tsx_async_abort=full mds=full l1ft=flush ipv6.disable=1" +cmdline="... slab_nomerge init_on_alloc=1 init_on_free=1 page_alloc.shuffle=1 pti=on randomize_kstack_offset=on vsyscall=none debugfs=off module.sig_enforce=1 lockdown=confidentiality mce=0 loglevel=0 iommu=force spectre_v2=on spec_store_bypass_disable=on tsx=off tsx_async_abort=full mds=full l1ft=flush ipv6.disable=1 rd.shell=0 rd.emergency=reboot" ``` After reconfiguring `kernel-hooks` try to reboot and it should boot. Although there are more options that might make the system more secure, these come with a big performance hit most of the time so these settings should do for now.
