On successful # extraction of physical address it wrongly sets "handled = 1" which # means this UE error has been recovered. Since MCE handler gets return # value as handled = 1, it assumes that error has been recovered and # goes back to same NIP. This causes MCE interrupt again and again in a # loop leading to hard lockup. # # Also, initialize phys_addr to ULONG_MAX so that we don't end up # queuing undesired page to hwpoison. # # Without this patch we see: # Severe Machine check interrupt [Recovered] # NIP: [000000001002588c] PID: 7109 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffd2755940 # Physical address: 000020181a080000 # ... # Severe Machine check interrupt [Recovered] # NIP: [000000001002588c] PID: 7109 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffd2755940 # Physical address: 000020181a080000 # Severe Machine check interrupt [Recovered] # NIP: [000000001002588c] PID: 7109 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffd2755940 # Physical address: 000020181a080000 # Memory failure: 0x20181a08: recovery action for dirty LRU page: Recovered # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # Memory failure: 0x20181a08: already hardware poisoned # ... # Watchdog CPU:38 Hard LOCKUP # # After this patch we see: # # Severe Machine check interrupt [Not recovered] # NIP: [00007fffaae585f4] PID: 7168 Comm: find # Initiator: CPU # Error type: UE [Load/Store] # Effective address: 00007fffaafe28ac # Physical address: 00002017c0bd0000 # find[7168]: unhandled signal 7 at 00007fffaae585f4 nip 00007fffaae585f4 lr 00007fffaae585e0 code 4 # Memory failure: 0x2017c0bd: recovery action for dirty LRU page: Recovered # # Fixes: 01eaac2b0591 ("powerpc/mce: Hookup ierror (instruction) UE errors") # Fixes: ba41e1e1ccb9 ("powerpc/mce: Hookup derror (load/store) UE errors") # Cc: stable@vger.kernel.org # v4.15+ # Signed-off-by: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com> # Signed-off-by: Balbir Singh <bsingharora@gmail.com> # Reviewed-by: Balbir Singh <bsingharora@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 75ecfb49516c53da00c57b9efe48fa3f5504a791 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc85xx_cds_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/mpc8555cds.dtb: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) arch/powerpc/boot/mpc8548cds_32b.dtb: Warning (pci_bridge): /pcie@e000a000/pcie@0: missing bus-range for PCI bridge arch/powerpc/boot/mpc8548cds_32b.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' arch/powerpc/boot/mpc8541cds.dtb: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) INFO: Uncompressed kernel (size 0x4de564) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4de564) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4de564) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4cdeb8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.17.0-rc2-g75ecfb4 Created: Tue Apr 24 15:40:59 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2509069 Bytes = 2450.26 kB = 2.39 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.17.0-rc2-g75ecfb4 Created: Tue Apr 24 15:40:59 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2533027 Bytes = 2473.66 kB = 2.42 MB Load Address: 00500000 Entry Point: 0050020c Image Name: Linux-4.17.0-rc2-g75ecfb4 Created: Tue Apr 24 15:40:59 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2534242 Bytes = 2474.85 kB = 2.42 MB Load Address: 00500000 Entry Point: 0050020c Image Name: Linux-4.17.0-rc2-g75ecfb4 Created: Tue Apr 24 15:40:59 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2533023 Bytes = 2473.66 kB = 2.42 MB Load Address: 00500000 Entry Point: 0050020c Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_mpc85xx_cds_defconfig_powerpc-5.3 # Build took: 0:00:36.051514
