Following, as I am experiencing a similar issue.
Removed some lines, as it's ~22 lines long. For my system, I'm using an R9 5900 (non-x), which is not listed as supported by my board, but this issue has only recently started for me. I was getting >4 month uptime until about 2 months ago. Nothing has changed since then, other than updating plugins and whatnot.
Based on "SB.PCI0" in the error, it looks like it's related to a PCIe device? PCI0 is where my X520-DA2 is located currently. When my server goes offline, I am unable to reach it via the network. I haven't been home when this occurs to see if it is responsive other than network. Like other posts, there doesn't appear to be anything in /var/log/syslog (and by extension, /boot/logs) that states anything about a kernel issue, and the ACPI issue only reads during boot.
If nothing else, I hope that my diagnostics have similarities to OP's so that we can find a solution.
