That message is harmless, it's just caused by ordering issues. The ips driver is built into the kernel but requires functionality from the i915 driver which is modular. You can see the feature re-enabled later in the log: [ 59.820433] intel ips 0000:00:1f.6: i915 driver attached, reenabling gpu turbo I'll send a patch upstream to fix the message severity.
Actually, intel_ips isn't built in, it's also modular, but the ordering issue remains.
