This silences all kernel messages below error-level, not just IBM0068.
In 2024, a patch was proposed to the Linux kernel mailing list to downgrade the IBM0068 message from KERN_WARNING to KERN_DEBUG , effectively hiding it by default. As of kernel 6.8+, you may still see it, but future kernels (6.10+) may finally silence it natively. acpi ibm0068

On some Gentoo or Arch Linux builds with custom kernels, a miscompiled ACPI table can cause a real error where IBM0068 returns AE_NOT_FOUND . This requires recompiling the DSDT—a process far beyond this article, but it affects fewer than 0.01% of users. Name (_HID, "IBM0068") // Hardware ID Name (_UID,
