Would be strange if dmesg was really truncated like that. I doubt that if ssh
still works. Armando, could you make sure that the log after resume is the full
output provided by dmesg?

The first dmesg attached to this bug resumes properly, HDMI display is enabled
during resume and then after a 5 second delay there is a modeset disabling the
display. That modeset looks like coming from user space. Is this also
reproducible from an FB VT console?
