#181882 — watchdog did not stop (on rebooting)

I was trying to find a way to fix this warning on my Thinkpad. I have 
found out that it is normal for this to happen and can safely be ignored.

Reference links:

https://unix.stackexchange.com/questions/249654/message-at-shutdown-watchdog-did-not-stop

However, if I set reboot-acpi AND irqpoll (in GRUB_CMDLINE_LINUX in 
/etc/default/grub) on a ThinkPad T61 (my computer), I get this error:

"CPU pipe B FIFO underrun"

So naturally I don't set reboot-acpi! :) (I was experimenting in trying 
to get rid of the watchdog warnings but gave up as it seems harmless and 
won't go away anyway).

Just thought I'd share this in case others run into these things.

#181903

If you have a thinkpad and use tlp you can set the NMI watchdog to off
in /etc/default/tlp

also look at /proc/sys/kernel/nmi_watchdog to see the state
