Error at jetson xavier startup , Failed to start load kernel modules

What change have you made?

Please check if can find reference from NVIDIA Jetson Linux Developer Guide : Audio Setup and Development | NVIDIA Docs

Thank you for your reply. I installed the ch340 driver. This problem occurred after the shutdown and restart. Can you help me solve it? I’m going crazy
demesg

Issue still happened if unstalled the driver?

yeah, what should i do next

Actually, we’re not sure what have been done on your device.
And if uninstalled the Ch340 driver sitll happened, I will suggest to reflash your device to a clean build which is Nvidia provided JetPack SW.
