I’m also suffering from the PCIe bus errors mentioned here Threadripper & PCIe Bus Errors and pci_aspm=off seems to make them go away. But my threadripper system has some weird performance characteristics that I don’t have the knowledge to debug. My problem is that quite often I experience system CPU usage spikes. The problem gets worst after waking up from suspend (to RAM). Linking executables also takes quite alot of time. I suspect there is some I/O issue.
- I’ve tried many kernel versions (up to 4.15.2) and nothing seems to help.
- I’m booting using Legacy mode (UEFI is disabled from bios).
- Apart from CPU+mobo+ram+PSU my workstation is the same as my older setup that used to work fine. Same HDDs, SSDs, GPU, software
Anyone else experiencing similar issues? Or do you have any idea how to debug the issue? Thank you in advance.
