Linux kernel 4.7.5
desktop  kde plasma 5
xorg-x11-server 7.6
libdrm_nouveau2  2.4.70
xf86-video-nouveau  1.0.13

System was coming out of suspend, and I typed in my password to the unlock
screen.  The mouse would move but the system locked up.  I couldn't switch to
another virtual terminal.

I remote logged in but I couldn't exit several processes including Xorg.
Many processes were waiting on 'SyS_po' or 'SyS_ep'.
I don't know if the nouveau fifo read fault error is valid as it does often.
