Re: Detecting NUMA per pmem

Hi A few more updates: a) This issue does not happen a lot I need to do a lot of power cycles for this to happen. b) We use 2 numa nodes but for some reason it happens only on the second numa. c) We added a debug feature that when page fault occurs we will trigger a thread from command line in the kernel(through configfs) that will read from any physical address that we give it. When we give it the faulty address - the thread succeeds reading from it with no page fault. We verified that it accessed the same virtual address that caused the page fault.
