So aside of all the software devices which we can (and really should) fix; these: 26.470076] pci0000:00: has invalid NUMA node(-1), default node of 0 now selected. Readjust it by writing to sysfs numa_node or contact your vendor for updates. 26.815436] pci0000:7b: has invalid NUMA node(-1), default node of 0 now selected.
