Hello Jonathan, this is a very similar problem on an T41 I had with 4.3... but it disappeared with 4.4 and it is not present now, running -current
What I always did was to ctrl+alt + F1 (or 2, 3.. ) and suspend from there with zzz I suspect it had to do with X ... because this worked well for me always. many greetings!
