Hi, This problem yet not happen when switched from CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y to CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y so it seems a CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS related problem. > $grep HUGE /boot/config-5.10.29-3.el7.x86_64 > CONFIG_CGROUP_HUGETLB=y > CONFIG_ARCH_WANT_GENERAL_HUGETLB=y > CONFIG_ARCH_ENABLE_HUGEPAGE_MIGRATION=y > CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE=y > CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE_PUD=y > CONFIG_HAVE_ARCH_HUGE_VMAP=y > CONFIG_ARCH_WANT_HUGE_PMD_SHARE=y > CONFIG_TRANSPARENT_HUGEPAGE=y > # CONFIG_TRANSPARENT_HUGEPAGE_MADVISE is not set > CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y > CONFIG_HUGETLBFS=y > CONFIG_HUGETLB_PAGE=y Best Regards Wang Yugui (wangyugui@xxxxxxxxxxxx) 2021/04/15
