Recently the server has been wanting to reboot itself. It started after I tried to install a second video card into the 2nd PCI-E X16 slot but it's IOMMOU grouping forced me to turn on the PCIE ACS override. Turning that on caued my parity drive to just disapere from the system and made the system lock up. So, took that out and turned ACS off. Stopped the array, got the parity drive back in, and started the rebuild and it wants to reboot iself when the rebuild started. I have a HiveOS VM that runs one Radeon 5700 in the top PCI-E slot that I've been running. When the server reboots it turns VM functinonality off.
System is a MSI B550 Tomahawk with a Ryzen 7 5800X, 32gb (4x8gb) DDR4 3600, Radeon 5700 reference, 2x 8tb WD Red, 1x8tb Toshiba 8tb, 500gb SK Hynix SATA SSD, and a 1tb Mushkin Pilot-E. It's probably not the best board for the job, but it was on sale, available, and my ASUS B550 board died and was out of warranty.
Thanks guys
