In x= mon I see one cpu in pmdp_invalidate and another in handle_mm_fault. It seems v= ery possible this is the bug that Nick Piggin's recent patch series fixes ("powerpc/64s: Fix THP PMD collapse serialisation"): http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=3D112348 --=20 You are receiving this mail because: You are watching the assignee of the bug.=
