September 21, 2025Sep 21 I've been having issues with my Unraid server for a while but just haven't had time to investigate. Until yesterday when I forced to make time because it wouldn't boot up. Turns out, the flash drive had gone bad. So I replaced it with a new one using a backup. I was hoping that replacing the flash drive would solve all the random issues I've been having but at least one issue persists; parity checks stall and never complete. In the logs I see a ton of the same warning repeated over and over again as well as one error. According to this thread (https://forums.unraid.net/bug-reports/stable-releases/61210-kernel-bug-at-driversmdunraidc1617-r2973/), it sounds like it might be a hardware issue. Are the warnings and error related? I'm not sure which device the warnings are referring to but maybe that can help me pinpoint the specific hardware that is causing the problem. Or is it something completely different?Sep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: AER: Multiple Corrected error message received from 0000:00:1a.0Sep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)Sep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: device [8086:7a48] error status/mask=00000001/00002000Sep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: [ 0] RxErrSep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: AER: Multiple Corrected error message received from 0000:00:1a.0Sep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)Sep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: device [8086:7a48] error status/mask=00000001/00002000Sep 21 02:10:21 Genesis kernel: pcieport 0000:00:1a.0: [ 0] RxErrSep 21 02:14:47 Genesis kernel: pcieport 0000:00:1a.0: AER: Multiple Corrected error message received from 0000:00:1a.0Sep 21 02:14:47 Genesis kernel: pcieport 0000:00:1a.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)Sep 21 02:14:47 Genesis kernel: pcieport 0000:00:1a.0: device [8086:7a48] error status/mask=00000001/00002000Sep 21 02:14:47 Genesis kernel: pcieport 0000:00:1a.0: [ 0] RxErrSep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: AER: Multiple Corrected error message received from 0000:00:1a.0Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: device [8086:7a48] error status/mask=00000001/00002000Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: [ 0] RxErrSep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: AER: Multiple Corrected error message received from 0000:00:1a.0Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: device [8086:7a48] error status/mask=00000001/00002000Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: [ 0] RxErrSep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: AER: Multiple Corrected error message received from 0000:00:1a.0Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: device [8086:7a48] error status/mask=00000001/00002000Sep 21 02:24:47 Genesis kernel: pcieport 0000:00:1a.0: [ 0] RxErrSep 21 02:26:46 Genesis kernel: ------------[ cut here ]------------Sep 21 02:26:46 Genesis kernel: kernel BUG at drivers/md/unraid.c:1617!Sep 21 02:26:46 Genesis kernel: invalid opcode: 0000 [#1] PREEMPT SMP NOPTISep 21 02:26:46 Genesis kernel: CPU: 22 PID: 21249 Comm: unraidd0 Tainted: P O 6.1.126-Unraid #1Sep 21 02:26:46 Genesis kernel: Hardware name: Gigabyte Technology Co., Ltd.

September 22, 2025Sep 22 Community Expert Solution The Unraid driver is crashing, this is almost always a hardware issue, typically bad RAM, or since you have a 13900K it could also be the CPU, look for a BIOS update, it may help if the CPU is nt too far gone, also, since you have multiple RAM sticks, try using the server with just one, if the same try with the other one, that will basically rule out bad RAM.

Do you think that is sufficient to rule out memory issues (assuming it completes the test with no errors) or should I pull different sticks as you suggested?Also I'm curious why a 13900K specifically would be a potential issue vs say any other CPU?
September 23, 2025Sep 23 Community Expert memtest is only definitive if it finds errors, since you have multiple RAM sticks, try using the server with just one , if the same try with the other one, that will basically rule out bad RAM.11 hours ago, axg1010 said:Also I'm curious why a 13900K specifically would be a potential issue vs say any other CPU?That CPU, together with the 13700K, 14700K and 14900K, is the most affected one by the Intel 13/14 gen issue. There have been many confirmed cases of those being the problem when having stability issues.

I did a deep dive into the issue and I'm really shocked how bad intel messed this up. I updated the BIOS and was able to complete a a parity check, so I think that's a pretty good indication that the CPU is the problem. Hopefully I can RMA it 😟
