Hi all. Long time Unraid user here, 10 years approx running on an N54L which had developed an intermittent connection issue on bay 3, so switched yesterday to a HP Gen8 Microserver I got off a mate which he ran flawlessly for a decade or so himself. Migrated the drives and USB across fine, array is all good. But I'm getting an NMI issue which locks the entire system. Seen here from iLO: If I have an SSH session on the machine at the time, I also see these errors: Done a load of googling on it, appears the issue may be something OS initiated, possibly Intel VT-d related (I've disabled this on the BIOS but no effect). It's also not the CPU or Ram causing the issue I don't think, because I'm getting this with the standard Celeron it has installed, and also an upgraded i3-1265L V2, and also get the same issue with the standard issue HP 2GB memory stick (SmartMemory verified) and also the 2x8GB Kingston sticks I had in my N54L for 10 years, all throw the same error. Now, if I boot the machine without the unRAID USB in and just leave it sat there trying to PXE boot it doesn't throw this issue at all despite running for hours, so it's gotta be something in unRAID throwing it. Not sure what to do. I'm running 6.12 latest. I know I could upgrade to v7 but this is ancient hardware so I'd be amazed if that made any difference but I will if required. Anyone got any ideas? Really just want to get my NAS back up and running I've got TV shows to watch Thanks in advance for any replies/help anyone can offer.
