Hi, A soft lockup issue was found during some SGX testing and it turned out to be a problem in SGX code related to NUMA, please see patch1/2 for details. While Dave reviewed v1 of patch1/2, he suggested dumping an info when a node has both CPUs and memory but no EPC section, so that's patch2/2. Comments are welcome, thanks. v2: - Enhance changelog for patch1/2 according to Kai, Dave and Jarkko's suggestions; - Fix Reported-by tag, it should be Gerardo. Sorry for the mistake. - Collect review tags. - Add patch2/2.
