This patch touches the NMI watchdog every MAX_ORDER_NR_PAGES to inhibit the machine from triggering an NMI while the CPUs are locked. This situation is happening on boxes with more than 64CPUs and 128GB of RAM when Alt-SysRq-m is performed. It has been succesfully tested for regression on uni, 2, 4, 8 32, and 64 CPU boxes with various memory configuration. Signed-off-by: Andi Kleen <ak@suse.de> |
