How to get debug information?
I'm testing the new Nvidia driver module with drm enabled. It is very
experimental so I know there are bugs in it. I think I found a problem and
I want to get more information about it from the log messages, but the
whole system freezes. I can't ssh into the system or change to a tty.
After a hard reboot the last lines in journalctl are:
kernel: usb 2-1.7: current rate 0 is different from the runtime rate 48000
Failed to get journal fields
Not very useful
Is there a way to get more information?
