Ok, it wasn't a hidden oops. The DISABLE_CONSOLE_SUSPEND=y thing sometimes shows oopses that are otherwise hidden, but at other times it just causes more problems (hard hangs when trying to display something on a device that is suspended, or behind a bridge that got suspended).
In your case, the screen output just shows normal resume output, and it apparently just hung for some unknown reason. It *may* be worth trying to do a SysRQ + 't' thing to see what tasks are running (or rather, not running), but since you won't be able to capture it, it's probably not going to be useful.

It would be interesting to see what triggered it, since it apparently worked before. So yes, a bisection would be great.
