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)

    I think You’re right, it is a mediatek chip and I used to add the USB device id manually to load the module, but with nixos 23.11 it started working automatically. I’m also running a preemptable kernel… Probably related now that I think about it :P

    I should track down the firmware, that was one of the things I was looking into when setting up the device id hack.

    I think this happened once before after uptime of about a week… But I didn’t get any information from that crash. Also, I’m remembering that some configurations were failing to see this wifi device and falling back to wired so maybe this has been a hidden problem since the new nixos release…

    Thanks to everyone for your thoughts, it’s very helpful.
