You may want to take a quick look at it now. I certainly don't mean
you should push aggregation aside, but the log looks kind of screwy at
18:28:43 (look at line 4972 to see what I mean). It looks as though it
did printk()s from multiple threads with no locking mechanism. It's
possible I will need to re-capture the error, and I'd like to know if
this log will help or not.
