Edit your bootloader (GRUB or systemd-boot) and append: lpro aio ramdisk device not registered better
Remember: The word "better" in the error log is a developer’s note to themselves. Your job is to give the system a "better" way to register that device—and now you have the tools to do exactly that. If this guide helped you, share it on forums or GitHub issues. If the error persists, post your dmesg output, kernel version, and distribution details in a comment below or on a relevant subreddit like r/linuxquestions.
Last updated: May 2026 – Compatible with Linux kernels 5.4 through 6.12. Add boot parameters to allocate contiguous memory or
sudo mkinitcpio -P If the standard brd (block ramdisk) driver is conflicting, blacklist it to allow LPRO to register its device:
# Ubuntu sudo apt install linux-image-generic-hwe-22.04 sudo dnf upgrade kernel Arch sudo pacman -S linux-lts If the error persists, post your dmesg output,
For 95% of users, rebuilding the initramfs with the proper LPRO and AIO modules—and optionally blacklisting the conflicting brd driver—will resolve the error immediately. For the remaining 5% working with legacy or custom hardware, a kernel patch or boot parameter adjustment will bring stability.
