After further testing, it seems that it only caused the issue to be delayed.
An hour and a half after I submitted the patch, my system crashed.

I mentioned this on the LKML thread but I forgot to mention it here.

I have a suspicion that the same state is being committed twice. I'll have
to investigate this further though. Once I determine if it is, I'll report
back on here and perhaps that will help with a bug fix.
