So Im seeing these pr_debug messages from kernel/module.c [ 624.888832] dyndbg: 336 debug prints in module i915 [ 624.891526] module:find_symbol: Failed to find symbol i915_gpu_busy [ 624.891528] module:find_symbol: Failed to find symbol i915_gpu_lower [ 624.891530] module:find_symbol: Failed to find symbol i915_gpu_raise [ 624.891532] module:find_symbol: Failed to find symbol i915_gpu_turbo_disable [ 624.891534] module:find_symbol: Failed to find symbol i915_read_mch_val [ 624.891537] module:find_symbol: Failed to find symbol intel_gvt_register_hypervisor [ 624.891539] module:find_symbol: Failed to find symbol intel_gvt_unregister_hypervisor Best I can tell (from local experience, running this kernel) this is not a big-time hard failure. But what is going on? they all appear by name to be functions, not data
