This is undesirable because they can trigger # any number of watchdogs while waiting for reboot, but also we don't # know what else they might be doing -- they might be causing trouble, # trampling memory, etc. # # The opal scheduled flash update code already ran into watchdog problems # due to flashing taking a long time, and it was fixed with 2196c6f1ed # ("powerpc/powernv: Return secondary CPUs to firmware before FW update"), # which returns secondaries to opal. It's been found that regular reboots # can take over 10 seconds, which can result in the hard lockup watchdog # firing, # # reboot: Restarting system # [ 360.038896709,5] OPAL: Reboot request... # Watchdog CPU:0 Hard LOCKUP # Watchdog CPU:44 detected Hard LOCKUP other CPUS:16 # Watchdog CPU:16 Hard LOCKUP # watchdog: BUG: soft lockup - CPU#16 stuck for 3s! [swapper/16:0] # # This patch removes the special case for flash update, and calls # smp_send_stop in all cases before calling reboot/shutdown. # # smp_send_stop could return CPUs to OPAL, the main reason not to is # that the request could come from a NMI that interrupts OPAL code, # so re-entry to OPAL can cause a number of problems. Putting # secondaries into simple spin loops improves the chances of a # successful reboot. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Reviewed-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 f2748bdfe157343eb8cf910a1d89ccf2fd20100b # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_bluestone_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 44x/bluestone_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_44x_bluestone_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here Completed OK # rm -rf /kisskb/build/powerpc-next_44x_bluestone_defconfig_powerpc # Build took: 0:00:21.778527
