NUC7PJYH No recovery from S3 in Linux

[arfultoucher]

Preface: I posted here while ago about a faulty unit (flash memory). Got advice to get it replaced. Meanwhile replacement arrived and it does not show that old issue. So this was a manufacturing fault.

The issue below is with the replacement NUC.

I have successfully flashed JY0047.bio (since I need CIR under Linux). The unit seems to work fine, except that it does not recover from S3. The disk spins up but the screen remains dark.

I tried with Ubuntu 18.10 and Lubuntu 18.10. There is no difference if the monitor is connected to HDMI-1 or HDMI-2. I suspect this is not a graphics driver or HDMI issue because

1) When I execute

echo mem > sys/power/state; echo hello > somefile

then somefile does no exist after I tried to wake up and then reboot the NUC.

2) I cannot ping the NUC from another machine after the broken wake up step.

Any help?

Since the OS itself does ot recover from S3, I suppose the problem is (related to) BIOS. If the exact cause and a solution is currently not known, is there a BIOS version for NUC7PJYH which is known to work with Linux and S3?

arfultoucher, Thank you for posting in the Intel® Communities Support. Just to let you know, Intel® officially validated the Intel® NUC Kit NUC7PJYH with Windows* 10-64 bit. However we have reports from "Canonical" stating that they were able to install and use Ubuntu 16.04 LTS as you can confirm in the following link: https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html As an option, you can always get in contact directly with Canonical and with Ubunto * forums for further assistance: https://www.ubuntu.com/support https://ubuntuforums.org/ In this case even though Ubuntu 18.10 / Lubuntu 18.10 are not validated by Intel® as supported operating systems, we will do further research on this matter in order to try to find a possible solution for this problem. Please let us know the results of contacting the forums provided above and as soon as I get any updates from our research I will post all the details on this thread. Regards, Alberto R.

I see. To be honest, I am a bit surprised that Intel doesn't put more focus and resources to Linux compatibility of their popular NUC products. After all, I guess many customers plan to do a bit more than plugging in their own SODIMM and disk and then installing the dominant proprietary OS.

Hi,

did you try with the OS selection set to windows in the bios?

I can remember that it did not work, when Linux is selected.

@KEgal​ you gotta kidding me!!!! That f***ing works!!! I had tried so many things in the BIOS. I thought the Boot->windows/linux switch had only sth to do with EFi and booting!! Thank you my dear friend! I owe you a beer or two!! @PatS_Intel​  please take note and have this documented wherever you think it should. Kudos to @KEgal​ !!
