Help w/ crash (lemmy.world)

Any advice on where to go from here? This console was running dmesg -w to try and catch an intermittent crash... And this is what I got. I am using an el cheapo USB wifi adapter that I'm suspicious of.

Everything was working fine until I rebuilt nixos with Nvidia support... Now my old generations of the OS are crashing after a few minutes (display on, no response to input, keyboard lights don't respond, SysRq doesn't work)

Looks like dmesg isn't being logged to disk... But I made my font smaller 😹 Definitely more to go on there, this happened while playing Minecraft with a small human so I didn't dig into it yet. I'm pretty sure the kernel I'm running was built by a derivation that applies some preempt patches so I'll start there. Ubuntu works fine with the adapter, but it's also not a preemptable kernel.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
