[Bug 2104936] Re: Freeze (Ubuntu 25.04 loading screen) on the first loading after installation

Three issues there:

1. The i915 kernel driver is crashing(?) on startup (I've seen this in
another bug report too):

i915 0000:00:02.0: [drm] Port B asks to use VBT vswing/preemph tables

2. The Bluetooth kernel driver is taking 20-30 seconds to start up
(download firmware?).

3. Again "nvidia: Spawned process '/sbin/modprobe nvidia-drm' [870] is
taking longer than 59s to complete." but that could just be caused by
#1.

So overall it's probably a kernel bug. Certainly the workaround you
mention in comment #7 just sounds like booting an older kernel version
that's free of the bug(s).

Bug description:
After having a strange issue on installation (the installer asked me
if I wanted to restart, I clicked yes, it closed, but nothing
happened. I had to shutdown the live OS myself. Maybe I should have do
a 'ubuntu-bug' before rebooting, but by the way I don't know if I had
to choose 'installation' or 'installer').

On the first boot of ubuntu 25.04 beta the loading screen (computer
logo + ubuntu logo) was like freeze. After waiting 1 min then doing
CTRL+ALT+DEL, now the OS does boot fine (tried 3 times).
