Date: Mon, 9 Jul 2007 10:02:42 -0400 From: Konrad Rzeszutek <konrad@...nok.org> To: linux-kernel@...r.kernel.org Subject: [PATCH] Inhibit NMI watchdog when Alt-SysRq-T operation is underway. On large memory configuration with not so fast CPUs the NMI watchdog is triggered when memory addresses are being gathered and printed. The code paths for Alt-SysRq-t are sprinkled with touch_nmi_watchdog in various places but not in this routine (or in the loop that utilizes this function). The patch has been tested for regression on large CPU+memory configuration (128 logical CPUs + 224 GB) and 1,2,4,16-CPU sockets with various memory sizes (1,2,4,6,20). - 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/
