[SOLVED/PATCHED] NUC6i5SYK do not shutdown correctly, sometimes it reboots

[jb]

Hi.

I open a new thread with the same problem I had in NUC6 since the version alpha2 of easyvdr 3.

The problem is that when I press the shutdown button in the remote, the NUC seems to be shutting down, but it reboots. When the first (sometimes the second) reboot is done, I press again the shutdown button in the remote and the NUC, then, shuts down correctly.

I thought that it was a kernel or BIOS problem, but I have the stable version of easyvdr 3, and the kernel is updated an so is the BIOS (I will check this week again, because there are updates every a short period of time).

If I can upload some info that can be useful to know which the problem is, I will be pleased to post it. Intel people seems not to be willingly enough in their forum.

Regards.

Hi, 
I think your remote is not working correct. 

Sometimes it seems to use keyboard buttons, and Power seems to use reboot (as strg+alt+entf). 
You can disable this via lirc. Conf or remote. Conf

Hello Javier


This is the command for shutdown your vdr:

Code:

sudo init 0

works it?

Hi, I do not think that it was the problem, because if I connect by ssh and run the command:
sudo shutdown -h now

The first time the NUC reboots, and if I connect again and run again the command, the NUC shuts down. Just in the same way that pressing power buton in the remote.

Hi Bleifuss2.

It happens the same than when I press power buton in the remote, and equal if I run "sudo shutdown -h now". The first time it reboots, the second or the third time I repeat the command in the command line is when the NUC shuts down.

Hi Javier

It's not a Linux Bug:

Hi.

Thanks, then it seems the NUC6 under certain circumstances do not shut down properly, and it seems to be an intel unsolved/undetected problem.

I have another NUC6 at home with ubuntu 16.04 and Windows 10, but it works fine. This problem has never happened on it. So, may be it not affect to all the NUC6 computers.

Then may be I need another solution. I think that a solution can be a script that check during boot if a shutdown has been tried, if the boot is made after a shutdown process the script should force to do another shutdown (checking recordings or scheduled tasks) till the NUC shuts down definitely.

The problem is that I do not know how to implement it.

The idea is:

1) (script 1)When the shutdown button is pressed (in case of recordings, when the button is pressed and the recordings are finished), make a new file named: "shutdownButtonPressed", in "/home/easyvdr/".
2)  (script 2)When the computer starts, check if the file "shutdownButtonPressed" is newer that 15 minutes. In that case, force a shutdown again (checking recordings or secheduled tasks)==> Simulating the power buton action.

Then, when the NUC reboots after a shutdown it will detect a recent version of the  "shutdownButtonPressed" file and it will shutdown again a second, or even a third time if needed, till the complete shutdown.

What do you think. It is possible to work? Can someone help me to implement the scripts?

Regards.

Try first a simple workaround:

60s after vdr is running, simulate press power button.
The vdr osd shows a waring , you can break power off with any remote key.
If a recording is activ the osd shows a message that vdr can't suhtdown now.


Adding this code after your remote fix modprobe ....

Code:

sleep 60 # Change the time as you like it
svdrpsend HITK Power >/dev/null 2>&1

Hi Bleifuss2.

It seems to work, but I have to test it after a sheduled recording, and I should improve the checking of the age of the checking file.

I created this file:

Code:

/usr/share/vdr/shutdown-hooks/95_createShutdownFile.sh

with this content:

Code:

#!/bin/bash
FILESHUTDOWNBUTTONPRESSED=/home/easyvdr/shutdownControl/shutdownButtonPressed;
rm $FILESHUTDOWNBUTTONPRESSED
touch $FILESHUTDOWNBUTTONPRESSED
exit 0

and I have created also this file:

Code:

/home/easyvdr/checkIfShutdownIsRequested.sh

with this content:

Code:

PATHFILESHUTDOWNBUTTONPRESSED=/home/easyvdr/shutdownControl/
if test "`find $PATHFILESHUTDOWNBUTTONPRESSED -mmin +5`" ; then
    echo "File is older than 5 minutes"
else
    echo "File is newer than 5 minutes"
    sleep 15 # Change the time as you like it
    svdrpsend HITK Power >/dev/null 2>&1
fi
exit 0

and I added in:

Code:

/etc/rc.local

this line:

Code:

sh /home/easyvdr/checkIfShutdownIsRequested.sh

As I said, it seems to work and if NUC reboots it is able to shutdown again... and again till it remains shuted down.

But I do not like the second script to check if the file "shutdownButtonPressed" (it is the only one file inside its folder) is newer or older than 5 minutes.

May be some of you can give a better idea to check it.

Regards.

Hi Javier

A pretty solution.

a usefull file for verify:

Code:

/var/log/easyvdr/easyvdr-runtime.csv

Hi Javier,

...starts your VDR via remote control?

Hi.

Yes NUC6 starts from the remote.

Hi, 
Does it also behave like this, when you start it via a Timer. And/or via Powerkey?

Hi.

I think so, but I have not tested it.

Do you need me to test something about it?

Hi Javier,

over Lirc?

Hi.

No, I gess it is by mean the BIOS. The computer is shutted down completely but infrared port is able to start the computer by itself.

Hi.

As the scripts work even after a recording and they end shutting down the NUC, I can mark as solved the thread. Thanks a lot for your help.

Anyway, if you can propose some improvement in the checking of the age of the test file (5 minutes old is the limit) I will try it, because I don not like my solution and I think it should be improved.

Hi.

I want to share the new version of the scripts, I think those are smarter than the elder.

This script:

Code:

/usr/share/vdr/shutdown-hooks/95_createShutdownFile.sh

has this content:

Code:

#!/bin/bash

#File should be added to /usr/share/vdr/shutdown-hooks/

# Path of the folder to control shutdown
DIRECTORY="/home/easyvdr/shutdownControl/"
# Path of the file made to shutdown  computer several times if needed
FILESHUTDOWNBUTTONPRESSED="/home/easyvdr/shutdownControl/shutdownButtonPressed"

if [ ! -d "$DIRECTORY" ]; then
    #Folder is made if needed
    mkdir $DIRECTORY  
fi

#Make shutdown request file
rm $FILESHUTDOWNBUTTONPRESSED
touch $FILESHUTDOWNBUTTONPRESSED

exit 0

###End of the Script

and this script:

Code:

checkIfShutdownIsRequested.sh

has inside:

Code:

#!/bin/bash

# Path of the file made when power button is pressed in order to shutdown computer
FILESHUTDOWNBUTTONPRESSED=/home/easyvdr/shutdownControl/shutdownButtonPressed

DATE_FILE=$(stat -c %y "$FILESHUTDOWNBUTTONPRESSED")
DATE_FILE_UTC=$(date -d "$DATE_FILE" +%s)

NOW=$(date +%s)
TIME_DIFF=$(($NOW - $DATE_FILE_UTC))

#Check if the file is older or newer than 5 minutes (300 seconds)
if [ $TIME_DIFF -lt 300 ]; then
    echo "File is newer than 5 minutes"
    sleep 15 # Change the time as you like it
    svdrpsend HITK Power >/dev/null 2>&1
else
    echo "File is older than 5 minutes"
fi

exit 0
###End of the Script
