Thanks JorgeB, i blacklisted the i915 onboard graphics and so far i got no error message for at least 30 minutes. I will check again tomorrow morning if still no error is visible in syslog. After that i will test rebooting my system as this did not work after a couple of hours.

Yes, of course. Sorry for forgetting it.homenas1-diagnostics-20250701-2305.zip

I bought some months ago the Ugreen DXP 4800 Plus NAS and started using Unraid from the first day on instead of the build in Ugos operating system. With Unraid 7.0 the NAS wasn't usable at all, after just 48h the system hung and i needed to pull the power plug to restart (no reset button available!). With Unraid 7.1(.4) its stability improved a lot and it is mostly stable, but i can't run it "for months". Still a reboot isn't possible at all, i always need to pull the power plug because it doesn't reboot on its own. I'm wondering if i am the only one using this specific model with Unraid as i can't find any issues like mine. Unraid raises debug traces nearly every minute. Is the hardware defect or isn't this NAS model from Ugreen just not supported correctly by Unraid? These issues are in the log every minute: Jul 1 21:13:16 HomeNAS1 kernel: i915 0000:00:02.0: [drm] ERROR Writing dc state to 0x2 failed, now 0x0 Jul 1 21:13:18 HomeNAS1 kernel: i915 0000:00:02.0: [drm] ERROR GT0: GUC: mmio request 0x508: failure 30f/0 Jul 1 21:13:18 HomeNAS1 kernel: i915 0000:00:02.0: [drm] ERROR GT0: GUC: Unsuccessful self-config (-ENXIO) key 0x906 value 0xa9b800 Jul 1 21:13:18 HomeNAS1 kernel: i915 0000:00:02.0: [drm] ERROR GT0: GUC: CT: Failed to register RECV buffer (-ENXIO) Jul 1 21:13:18 HomeNAS1 kernel: i915 0000:00:02.0: [drm] ERROR GT0: GUC: CT: Failed to enable CTB (-ENXIO) After a "reboot" the log ist really fine, even for some hours, but after an unkown point these log entries are visible and are repeated continuously. Do you any suggestion for me why the Intel I915 has so man errors on my system? Thank you homenas1-syslog-20250701-1948.zip
