[SOLVED] Boot log insufficient

Hey,
I got the problem that the system gets stuck while booting and won't continue. There are numerous modules that fail to load with the most prominent being dbus. So I think it is a problem with systemd.
The standard output can't help me debug this and when I try to increase the details I cant scroll up far enough to read the relevant parts.
I checked Boot Debugging but I got no idea how to increase my buffer. log_buf_len=10M did not do what I was hoping for.

Can I write the output to a file or increase the buffer so I can scroll up far enough?

Thank you for help!

Re: [SOLVED] Boot log insufficient

In my syslinux.cfg I have

fbcon=scrollback:512k

at the APPEND line.

I know. I just added crossreferences to Boot debugging as if you google for it and don't know that the correct name is Scrollback buffer you find the boot debugging page but not the relevant information.

Ooohh, okay that does make sense.  I can agree that was a good idea.
