I have snice turned off CONFIG_TRANSPARENT_HUGEPAGE on 3 of 4 servers that had this problem (actually most of my sparc64 machines) and the 4th has
CONFIG_HAVE_ARCH_TRANSPARENT_HUGEPAGE=y CONFIG_TRANSPARENT_HUGEPAGE=y # CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS is not set CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y # CONFIG_HUGETLBFS is not set # CONFIG_HUGETLB_PAGE is not se
and also has not had this problem since then. All 4 machines have been running through most -rc's of every kernel.
