Alexstrasza Posted June 21, 2020 Share Posted June 21, 2020 Hi all, The past week or so I've been getting kernel panics on my server. This has definitely been happening on the most recent betas (6.9.0-beta1 and beta22) and may have been happening on the stable release as well. Unfortunately as the kernel panics, there are no logs of what was happening before or what went wrong, attached is the only screenshot I've been able to pull from the console screen. Any suggestions would be much appreciated. Quote Link to comment

JorgeB Posted June 21, 2020 Share Posted June 21, 2020 Make sure it's using the recommended power supply idle control setting. 1 Quote Link to comment

Squid Posted June 21, 2020 Share Posted June 21, 2020 If that fails, try dropping the memory speed from it's overclock setting of 3200 down to its native speed of 2666 1 Quote Link to comment

Alexstrasza Posted June 24, 2020 Author Share Posted June 24, 2020 Update: The server crashed again. I have now reset the RAM overclock so it's running at stock speeds. The panic does always appear to be in some kind of TCP stack, so that might be relevant if it crashes again. Quote Link to comment
Alexstrasza Posted July 1, 2020 Author Share Posted July 1, 2020 Final update: The server has not crashed again, so I can comfortably say that the problem was the overclocked RAM. Thank you everyone for your help! 1 Quote Link to comment
ocedric Posted July 3, 2021 Share Posted July 3, 2021 Hi Alexstrasza, I'm having the same issue, and it just happened at the end of my array rebuild 😕 Did the RAM speed setting solve the issue on the long term? No more Kernel Panic since then? Quote Link to comment

I've had quite a lot of general instability issues, the X470D4U motherboard seems to be plagued with issues, in particular reliability varies hugely BIOS to BIOS, so if you're running that motherboard then I heavily recommend the P3.50 BIOS firmware and 2.20.00 BMC firmware, which have been the most stable I've seen. It's also worth noting that future UnRaid versions have also improved other issues a lot, so I heavily recommend checking you are on the latest version as well. Quote Link to comment
