It's the first UML kernel I compile in a few years, so I don't know if
it's old or new, sorry.
Yes, only con=xterm triggers this.
(For the record, I also couldn't con=pty or con=pts to work either, it
just results in "Aborted." on the console where I ran ./vmlinux -- if I
try con1=pty or con1=pts it boots normally, but there is no message in
the kernel log indicating the host device that was used for the console.
But this could be a PEBKAC, I only mention it in case it might be
relevant. Also, normal ./vmlinux without any con*= arguments works fine,
but I only get the plain stdin/stdout console.)
Thanks,
Vegard
