Although the memory size of virtual machine is too small, your commit may increased memory usage. ========================================================================================= tbox_group/testcase/rootfs/kconfig/compiler/sleep: vm-intel12-openwrt-i386/boot/openwrt-i386.cgz/i386-randconfig-a0-201545/gcc-5/1 commit: 344c23116aa2003811927925a8462e57311e6467 c1a6680dfd43af25bdfd5a22a7fe6efc16ba56f6 344c23116aa20038 c1a6680dfd43af25bdfd5a22a7 ---------------- -------------------------- fail:runs %reproduction fail:runs | | | :30 50% 15:30 kmsg.Kernel_Offset:disabled 1:30 -3% :30 kmsg.hrtimer:interrupt_took#ns :30 50% 15:30 dmesg.Kernel_panic-not_syncing:Out_of_memory_and_no_killable_processes :30 50% 15:30 dmesg.Mem-Info :30 50% 15:30 dmesg.invoked_oom-killer:gfp_mask=0x ========================================================================================= tbox_group/testcase/rootfs/kconfig/compiler/sleep: vm-kbuild-yocto-i386/boot/yocto-minimal-i386.cgz/i386-randconfig-a0-201545/gcc-5/1 commit: 344c23116aa2003811927925a8462e57311e6467 c1a6680dfd43af25bdfd5a22a7fe6efc16ba56f6 344c23116aa20038 c1a6680dfd43af25bdfd5a22a7 ---------------- -------------------------- fail:runs %reproduction fail:runs | | | :36 72% 26:36 kmsg.Kernel_Offset:disabled :36 72% 26:36 dmesg.Kernel_panic-not_syncing:Out_of_memory_and_no_killable_processes :36 72% 26:36 dmesg.Mem-Info :36 72% 26:36 dmesg.invoked_oom-killer:gfp_mask=0x ========================================================================================= tbox_group/testcase/rootfs/kconfig/compiler/sleep: vm-vp-quantal-i386/boot/quantal-core-i386.cgz/i386-randconfig-a0-201545/gcc-5/1 commit: 344c23116aa2003811927925a8462e57311e6467 c1a6680dfd43af25bdfd5a22a7fe6efc16ba56f6 344c23116aa20038 c1a6680dfd43af25bdfd5a22a7 ---------------- -------------------------- fail:runs %reproduction fail:runs | | | :12 83% 10:12 kmsg.Kernel_Offset:disabled :12 83% 10:12 dmesg.Kernel_panic-not_syncing:Out_of_memory_and_no_killable_processes :12 83% 10:12 dmesg.Mem-Info :12 83% 10:12 dmesg.invoked_oom-killer:gfp_mask=0x vm-intel12-openwrt-i386: qemu-system-i386 -enable-kvm Memory: 192M vm-kbuild-yocto-i386: qemu-system-i386 -enable-kvm Memory: 320M vm-vp-quantal-i386: qemu-system-i386 -enable-kvm -cpu Haswell,+smep,+smap Memory: 360M Thanks, Ying Huang -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
