Hello hotwolf, I have read your message. I have a few questions:
- the message you get from NUC appeared after the installation of new hardware (like a USB Hub) ?
- the message you get from NUC appeared prior or after the installation of Linux FDE ?
- is your UEFI Firmware up-to-date (have you installed the last version) or did you recently installed a new firmware version ?
Anyway you can check the following links:
https://superuser.com/questions/904004/ ... t-attempts
http://www.aslab.com/support/kb/191.html
https://www.intel.com/content/www/us/en ... 1549670358
The first one recommend to answer 'Y' entering your UEFI/BIOS firmware and then commit 'Save and Exit'.
The second one recommend to change the kernel boot command line adding the option 'reboot= acpi' or 'reboot=t' and then re-booting many time until the message disappear.
The last one is from Intel and suggest to reload the default UEFI Firmware setting. Doing so you will probably lose you UEFI Firmware Secure Boot settings.
You can test these solution and eventually re-install the Linux FDE system. My first impression is that this warning message is due to hardware and/or firmware issues. So if you don't get rid of this problem with software 'escamotages' (like these explained in the first and second links) my advice is resetting your UEFI Firmware to default setting (as recommended by Intel) and then install the latest UEFI Firmware version. If doing so the warning message remain that is the proof that the problem is most likely due to a hardware and/or firmware problem.
Please keep me informed about your progress.
Regards.

Hello Linux22,
thanks for all the tips.
First to answer your questions:
I followed your links, and the first thing I've tried was to disable the "Failsafe Watchdog" option in the BIOS (as described here https://www.intel.com/content/www/us/en ... 1549670358). And this solved the problem right away. My NUC now boots right to the FDE password entry without any prior BIOS prompt. So I didn't even need to modify the kernel boot options.
Thanks again for your great help.

First to answer your questions:
I had an external DVD drive connected to my NUC, which I had used for the OS installation. I did remove at it some point later on. So the message may have come at some point after a change of hardware configuration.- the message you get from NUC appeared after the installation of new hardware (like a USB Hub) ?
I don't remember this message showing up after the Linux FDE installation. I think it started to pop up after I tried the secure boot setup.- the message you get from NUC appeared prior or after the installation of Linux FDE ?
I'm using version 2.2.23 of the Intel Visual BIOS, which my NUC was shipped with.- is your UEFI Firmware up-to-date (have you installed the last version) or did you recently installed a new firmware version ?
