January 21, 20251 yr I moved to a new server a couple weeks ago (UGreen DXP4800 Plus) and upgraded to Unraid 7.0. System was crashing every 24-48 hours with nothing suspicious in the local syslogs. This progressed to crashing every few hours, despite running in safe mode with everything disabled. I ran an extended memtest86+ (10 passes) so I think that rules out bad ram. Then I suspected failing USB drive so I replaced that. Still crashing. Finally I returned the UGreen system and replaced it with a fresh one assuming it was some unknown hardware issue. With the new system it ran fine for 24 hours but then crashed AGAIN, and nothing logged at all in the logs for the hour leading up to the crash. At this point I don't know what to do. I've essentially replaced all hardware, and it's still crashing. I have a monitor hooked up to it but when it crashes just showing a flashing/glitched version of the original boot sequence. Is there a way to have the monitor display the logs, to maybe catch something that's not being saved to the local syslogs? Or does anyone have any ideas of how to proceed? Thank you. green-diagnostics-20250119-0008.zip

Ok thanks I'll try that. Is the i915 iGPU issue still relevant? I've seen old threads talking about that causing crashes, but has it since been fixed?
January 21, 20251 yr Community Expert That can be hardware dependent, if you suspect it could be an issue, you can try blacklisting that driver: https://docs.unraid.net/unraid-os/release-notes/6.10.0#linux-kernel
