Oops, there are multiple devices in that trace.


I notice in the trace_report_180secs.txt file, lsn (ail_push and the 
ungrants) displays are not correct. It acts like the BLOCK_LSN() is 
shifting too much. Block sequence numbers never make it too far above 
1100 before incrementing the cycle. I think the problem is the trace not 
the sequence numbers.
