Did your kernel enable CONFIG_IO_STRICT_DEVMEM?

My System Artix Plasma openrc

following the command and the error message:
Code: [Select]
nvme show-regs -H /dev/nvme0
nvme0 failed to map. Did your kernel enable CONFIG_IO_STRICT_DEVMEM?

Can anyone help me to solve this issue?

Thanks in advance and best regards.

At least let us know what kernel you're currently running. Regardless, you can check it by yourself in /proc/config.gz
