[NVME drives throwing errors, filling logs instantly. How to resolve?]

The "pcie_aspm=off" kernel parameter hides a problem.  I would really like to fix the underlying problem so the parameter isn't needed.

 

If anybody is willing to help fix it, please open a bug report at https://bugzilla.kernel.org/, product Drivers/PCI, mention the hardware platform, and attach:

• complete dmesg log (I assume this will include some Correctable Errors)
• output of "sudo lspci -vv"

Try booting with the "pcie_aspm=off" kernel parameter to see if it makes any difference. If it does, please also attach similar dmesg and lspci output for this boot.

This seems similar to https://bugzilla.kernel.org/show_bug.cgi?id=215027, which we originally thought was related to Intel VMD and/or the Samsung NVMe device you have, but I now suspect we might have an ASPM configuration problem.

If you can run a v5.5 or newer kernel, try this to see if it's a workaround:

 

  # echo 0 > /sys/devices/pci0000:00/0000:00:01.2/0000:01:00.0/link/l1_aspm

If you can reproduce this problem and the workaround above works, please let us know at [email protected].  We would really like help to get this fixed.  The output of "sudo lspci -vv" would be helpful.
