From 860f01e96981a68553f3ca49f574ff14fe955e72 Mon Sep 17 00:00:00 2001 From: Valentin Vidic Date: Fri, 5 May 2017 21:07:33 +0200 Subject: ipmi/watchdog: fix watchdog timeout set on reboot systemd by default starts watchdog on reboot and sets the timer to ShutdownWatchdogSec=10min. Reboot handler in ipmi_watchdog than reduces the timer to 120s which is not enough time to boot a Xen machine with a lot of RAM. As a result the machine is rebooted the second time during the long run of (XEN) Scrubbing Free RAM..... Fix this by setting the timer to 120s only if it was previously set to a low value.
