--- Comment #20 from Larry Finger 2010-08-01 19:40:00 ---
The diagnostics patch from #12 did not change anything.
I am beginning to think that Bug 16312 is not the same as Bug 16122. Even with
the patches from 16312, I still get warnings as below:

The warnings do not occur with every boot and appear to be some kind of race
condition.
