Created attachment 75331 [details] [review] [review] [review] simple fix
Just this patch alone seems to fix the issue here.
I can still lockup with this
Ignore this - I messed up when testing simple fix and was testing unpatched
- it's running now and hasn't locked yet.
It eventually hard locked with nexuiz.
