I'm pulling my hair out here. I had an old trusty Dell Poweredge running my unraid and it was absolutely rock solid, but decided to 'future proof it' with my ever growing needs and moved it to an AMD 7800x3d based system. Since the upgrade, I can barely make a day without it hanging. I've already lost the ZFS cache partition twice now through corruption due to the crashing. I thought it might be memory, so I ran the memory test and it was fine. I thought it might be the Ryzen issue, so I am running with the cstate parameter and that didn't help. I have the logs and it always seems to be the same thing happening, I just don't understand how to read the logs to troubleshoot. Any help greatly appreciated. Attached the logs where it all goes bad. About 2 minutes before crashing I have the same errors coming out, then it hangs (crashing.txt).

Thanks for the reply. I had a look at this and looked around but I can't find anything that relates to 4th gen Ryzen and DDR5. I was thinking maybe the cstate issue was solved as nothing seems to mention issues with Ryzen anymore (that or my Google Foo is broken). 

 

 

Look in the board BIOS, also not sure if it's still an issue with Ryzen 7000, but there have been other reports of stability issues with those CPUs, possibly too new for the kernel.

So I still have not figured this out entirely, but what I did figure out is that it was the Coral AI USB TPU & Frigate that was causing the daily crashing. Since I have unplugged the Coral AI it seems to be OK now. So either just leave it out, or try work out why the Coral AI is crashing the system daily. It doesn't look isolated as I have found a few people with the same symptoms, sadly none with a fix.
