May 3 16:36:06 ubuntu systemd-modules-load: Inserted module 'lp'įrom this, I believe that Invalid argument is the last line before the system stopped responding. So I looked at syslog messages, narrowing down to the moments before the system crashed, and noticed: May 3 16:33:39 ubuntu fido_id: 1-12:1.0: Failed to open report descriptor at '/sys/devices/pci0000:00/0000:00:01.3/0000:02:00.0/usb1/1-12/1-12:1.0/report_descriptor': No such file or directory I checked dmesg to see what could've gone wrong, but I didn't find anything in there that indicates any type of problem.
The other difference is when my system locks up in 18.04, I'd still be able to ping or SSH into it, but in 20.04, the system would drop off the network altogether. This happened back in 18.04 as well, but not that often (like once every week or so, but now I've seen 4 crashes in the past hour already).
The problem is that sometimes, out of the blue, my machine would lock up. The OS is booting off a NVMe drive in UEFI mode. This is on a self built system with a Ryzen 7 1800x and a Gigabyte AX370 Gaming 5 motherboard. I started out with Ubuntu Server 20.04, then added GNOME to it for a minimal setup. This is on a fresh install of Ubuntu 20.04 on my desktop.
