I'm glad the board and PC are running again. Why that happened is unknown to me.
I'm not a Ubuntu person, but your UEFI installation description seems perfect.
Do you know if the version of Ubuntu you are using has a built in NVMe driver? I imagine it must or the 950 would not function as far as I know. Or if the NVMe driver in Ubuntu does not work well with the 950 Pro?
The Window native NVMe driver is known to have write performance issues with the 950 Pro, but is not known to caused instability. Samsung supplies an NVMe driver, but it is only available from Samsung with a Windows type installation program. Scroll down on this page to find that driver:

Apparently you can find the driver files with an Internet search, that have been extracted from the Samsung Windows installation program, but the drivers are Windows type driver files that are likely worthless to you. I doubt I need to tell you Samsung does not supply any non-Windows type drivers or software for their SSDs.
The EFI compatible Option ROM in the UEFI is supplied by Intel, but if it works with Ubuntu, I have no idea. NVMe SSDs cannot boot a legacy OS installation, and minimally must use the EFI boot loader.
Another typical UEFI OS problem is the video driver not being GOP compliant. I have no idea what your video source is, but the Intel integrated graphics has a GOP compatible VBIOS that is part of your board's UEFI/BIOS file.
Intel does provide a link to Linux compatible video drivers for their integrated graphics... which I can't find now, of course...![Confused]( "Confused")
