Thank you very much for sharing your issue with the Intel® Communities Team.
I understand your NUC is now restarting every 24H after a BIOS installation. Allow me to help you regarding this issue you are facing.
I would like to know if the page where you downloaded the BIOS version was the Intel® Download Center and which method you used to complete the installation.
By the way, I will highly recommend you to verify with your Operating System Support Team if they have any update on the Spectre and Meltdown issue as well.
Thx for taking care, Antony.
Yes, BIOS downloaded from here:
Attached the corresponding readme for 046.bio
Interesting: 046 from December 2017 is gone and now 045 ist latest. Anyway I flashed 046 via F2/F7 method to upgrade from 027 to 046. After that the 24h start issue begun. I tried CMOS/settungs wipe via bios options, disconnected the LAN cable but every 24h the system starts itself at the same time. After four days and various tests (disabling evverything WOL or power related) i downgraded to 026 (by accident) via F4 recovery and after that upgraded to 027 via the HW yellow jumper procedure. Though the 24h start up issue is still present.
btw, during the 026 to 027 upgrade I got an error message 'fwUpdateFullBuffer' . (see attachment). After that I upgraded by yellow jumper method.
Curently I'm more interested in getting back a system that does not start by itself every day. The OS mitigations will happen soon.
Thank you very much for your reply.
In this case, at this level of support, I am not able to provide a solution. I will escalate this case to a different level. Please be aware that it might take some time to have a solution.
Thank you very much in advance for your patience.
Meanwhile I did some changes to my config that solved the 24h restart issue - at least this is what it looks like.
These changes were not meant to be get into the root cause so maybe one or all of them helped. This is what I did (still with 027)
1. I disconnected the PSU for ~ 3h
2. Is set and unset the timer function the BIOS offers. I activated the function and let it start the NUC for exactly one time. After that I disabled it again.
3. I checked with ethtool the NIC settings. eth0 WOL flag was set to 'g'. This did not change after a reboot. So I added a 'ethtool -s eth0 wol d' into a startup shellscript - made me feel better :\
So whatever I did It solved the issue for the time being. I'm now 48h without a spontaneous NUC boot. And the IR-RC is still working :-)
Don't know if you will still look into it. If not I might flag this as 'magically' solved.
Thank you very much for sharing that information with our Community, I really appreciate it.
Please let me know if the issue persists after the steps you performed.
