This particular patch is still beging discussed on the LKML. This is the latest submission with improved variable naming, increased threshold and changes to the log and the warning message (as proposed by tglx): https://lore.kernel.org/lkml/20240122172350.GA740@incl/ Especially the change to the message is important. I think this message will be commonplace on 8 NUMA node (and larger) machines. If there is anything else I can do to assist please let me know. -- Jiri Wiesner SUSE Labs
