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.
