This is very probably separate problem... and you should have enough data in dmesg to do something with it.

What makes you say it's a different problem - it's hanging at the same point visually - it's just that one is pre suspend, one is post suspend.


It all feels very related to me - the behaviour all hinges around the same patch too.

I'll take a look in dmesg though...
