Comment 0 for bug 2012908

I just updated my Lunar install, which brought me the 6.2 kernel, and it failed to start, stalling after enumerating my USB devices, until something times out with a message saying that the udev event queue failed to be drained.

When attempting to move on to the normal graphics boot from rescue mode once the timeout is hit, I simply get a black screen.

I'm blaming this on the nvidia driver because of this appearing in the log:

Also, the last entry before I had to do a hard shutdown was this:

mars 27 10:34:54 gandalf systemd-udevd[1023]: nvidia: Spawned process '/sbin/modprobe nvidia-drm' [1124] is taking longer than 59s to complete

I'm attaching the kernel logs up to the beginning of userspace logs. I can provide more if necessary.
