Title pretty much says it all.
Some background - My previous system was an AMD FX-8320 with 8GB of RAM, pretty old so I decided to do a bit upgrade and bought myself a fancy new processor and whatnot. The full spec list is here (pcpartpicker). I went ahead and installed the hardware, keeping the same SSD that my Ubuntu 18.04 install runs off of (currently on kernel 4.18.7). But of course I’ve hit a bit of a snag.
Randomly, my desktop crashes completely, forcing me to do a hard reboot. Here’s what I believe are the relevant logs that happened right before I hard restarted my machine - I can’t make heads or tails of it since I’m not exactly a kernel/hardware guy but I want to at least find out what the root cause of this could be.
