hello aaron.ge,

according to your logs, the kernel is still running normally.
please check the backlight of your display monitor, since display controller still try to fetch information from EDID.
for example,

[28892.296559] tegradc 15210000.nvdisplay: hdmi: get RGB quant from EDID.
[28892.296568] tegradc 15210000.nvdisplay: hdmi: get YCC quant from EDID.

may I also know what’s reason to make sudden crash?
you should enable $ dmesg --follow, to track the root cause.
thanks
