[ TO TTY folks ] + [ CC Rafael and linux-pm ML ]

In the end it turned out to be a problem with tty-next (see thread in [1]).
I am hitting the problem reproducibly on PM/suspend.
Rafael gave me some cool help on pm-testing, thanks (see also thread in [1])

Ilya has sent a patch to [3] which needs to be refreshed.
AFAICS also be adapted to the recent changes to tty_port and tty_buf.
But hey, I am no TTY expert so it is up to you.

Hope you will CC me on the patch.

Thanks!
