Bug#974166: Boot logs

Cross-posted to 2 groups.

Show key headers only | View raw

I tried booting in recovery mode,
and it also didn't work.

However, I could see the some info.
The 3 last lines of the boot log were:

{
[    4.817936] hub 4-0:1.0: 2 ports detected
[    4.819372] i915 0000:00:02.0: [drm] Found 128MB of eDRAM
[    4.819882] fb0: switching to inteldrmfb from EFI VGA
}

And then freeze.
These messages are not logged into /var/log/kern.log,
as the system doesn't even boot.
I had to copy them by hand.

Here's what I see when booting with kernel 5.4
at (more or less) the same part of the boot process:
