Does it actually hand the machine, or do you get the warning and then
work continues?

Unfortunately your backtrace doesn't seem overly reliable, so it's kinda
hard to figure out what is going on.  There is nothing delaylog related
in the provided one though.  If it halfway matches what is going on it
seems to be block I/O related.
