I installed it on a different partition with fresh installation of Devuan and it works fine there

I installed intel-gpu-tools while using Devuan via the usb (live system) and 'intel_reg' worked fine there

Does reverting those GRUB & sysctl changes remove the error?

Btw I'm pretty sure kernel.dmesg_restrict is already enabled by default.

The only thing kernel related I did lately was adding a few lines to '/etc/sysctl.conf' and a few options to '/etc/default/grub'

vm.mmap_rnd_bits = 32
vm.mmap_rnd_compat_bits = 16
fs.protected_fifos = 2
fs.protected_regular = 2
kernel.dmesg_restrict = 1
kernel.printk = 3 3 3 3
kernel.kexec_load_disabled = 1
kernel.unprivileged_bpf_disabled = 1
net.core.bpf_jit_harden = 2
vm.unprivileged_userfaultfd = 0

slab_nomerge init_on_alloc=1 init_on_free=1 page_alloc.shuffle=1 pti=on vsyscall=none debugfs=off oops=panic module.sig_enforce=1 lockdown=confidentiality loglevel=0

Any ideas are highly appreciated!
