Recently on newer Nvidia drivers, I’ve been seeing segfaults/system hangs and PCIe error spam in dmseg. There doesn’t seem to be any real trigger for them - they just kind of happen. At first I thought it was a kernel bug introduced in 4.18 but not with 4.19 i’m not so sure…
No, the gpu is not involved, just affected. This looks like errors on the promontory bridge. While this is a standard flaw on the TR X399 chipset, I’ve never seen this on a Ryzen X370 chipset, looks like a HW failure of the mainboard to me. Maybe try the X399 workaround, if possible, in bios, set the promontory bridge to gen2 and add the kernel parameter pci=noaer
Might also be a system memory failure, don’t use memtest, just remove all memory modules but one, check, then swap.
You know, now that you mention it… when memory clock speed was set too high/wasn’t stable it was always the GPU that started going wonky in Windows. I didn’t even think about it until now because Windows worked fine. I’ve also been experiencing model flickering in Metro Redux in Linux which may be related. I’m using 32GB 2800Mhz(Corsair Vengence 3200Mhz).
Well, guess I’ll be decreasing my memory speed to see if it helps any…
