Re: dmesg kernel trace and base system without less/man (WAS: Re: debian-installer now available in Ports)

[Linux User #330250 <linuxuser330250@gmx.net>]

Hi!

No, I did not. If I did, I surely would have to compile a recent kernel 
to see if the error is still present, which I was not prepared for since 
I only tested the installer for an unofficial Debian PowerPC netinst image.

If time permits, I can still try a current kernel release (4.11; not the 
one from Debian: 4.9.x). Since my time is limited, I'd like to only do 
that when it seems necessary and needed, or rather: asked for. Is it 
needed? Then I will gladly make some time for this.
Which kernel? git or current stable from kernel.org?
Which config? Debian-provided or make defconfig?
Anything else I should look out for?

Cheers,
Linux User #330250
