 Hey Sean
 
 Two of the G7 blades stalled today, that was quick=85 Here's an alltrace =
 and ciss debug output each:
 
 First stall:

 /20130705%20-%20G7%20crash%201%20(12s)/20130705%20-%201%20-%20alltrace.txt=

 t
 
 Second stall:

 t
 
 As said, the debug information is for ciss0 only, because the driver =
 does not iterate through all controllers when printing debug =
 information. Also, if you need more information when this happens the =
 next time, please let us know.
