I just built my Ryzen server yesterday. It crashed sometime when I was unable to get to it. I have been watching the log and its spitting out this error a lot:
Jul 17 08:39:17 FatTony kernel: pcieport 0000:00:01.2: AER: Corrected error received: id=0008 Jul 17 08:39:17 FatTony kernel: pcieport 0000:00:01.2: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=000a(Transmitter ID) Jul 17 08:39:17 FatTony kernel: pcieport 0000:00:01.2: device [1022:15d3] error status/mask=00001000/00006000
Which correpsonds to this:
IOMMU group 1:
[1022:15d3] 00:01.2 PCI bridge: Advanced Micro Devices, Inc. [AMD] Device 15d3
Anyone else had this problem? On a B350 mobo.
Edit: After some googling and trying various things, I added pcie_aspm=off to my syslinux.cfg and the errors are not getting thrown around anymore. I will let it run and see if my system is stable now.
