Four different dmesg outputs during a hang with GPU soft reset enabled

I posted the previous comment too soon. The hang while using apitrace hangs
everything except the mouse cursor. I'm unable to switch to text mode (ctrl+f1)
and there is nothing new in dmesg other than the bootup messages (I was able to
get this via SSH).

As an aside, I've also attached 4 different GPU hang messages from dmesg from
various different hangs while I was playing TF2.
