Hit this again - system doesn't crash now - just get the hung task 
warning (log extract attached). System seems to keep running (albeit the 
rebuild is incredibly slow on 2.6.33 rc5 - approx 6500K/sec vs. about 
80,000K/sec on 2.6.32.4.

Looks like it may be triggered by disk io during the rebuild. This time 
I had typed, "sync." "sync" hung for a long while but did eventually 
complete.
