I usually build the AUR package from within X. But sometimes I do it on
another TTY. On these cases where I do it from TTY I was able to see
partly a core dump (messages about kernel panic and then some more
output). The problem was that it was part of it and I could not scroll
to see the whole message.

But that invoves a kernel compilation (right?) and I seem to end up in the same
problem as before - kernel crashing when compiling big projects.

Is there a kernel with Kdump enabled already?
