UM890 and DEG1 failure
I set this machine up with a SFF 780W PSU and a 6750XT. It's running Linux, specifically CachyOS. Memory is dual channel DDR5 kit, 48GB kit, Crucial memory. I have two monitors plugged into the computer using the eGPU using Display Port.
When I log in on the system, somewhat randomly, the screens go blank, and the GPU fans ramp up to 100%, the USB goes dead, and the system will reboot, but without the GPU being turned on, or the DEG1 powering up.
There's absolutely nothing in the jornalctl log, it literally just stops and shows the boot process starting.
This is really frustrating, I'm about to give up on the entire machine, I need it to be reliable, but it just isn't.
Before I start chucking parts at this, does anyone have any suggestions or wisdom on this?
