Follow-ups

 

--- Bob Liu                                                  2011-04-15 01:45:10

It's not a bug.

The kernel asks the SCSI drive for its cache parameters.

And the raid card sitting in the middle doesn't know how to handle this so this

 

message occurs.

 

--- Vivi Li                                                  2011-06-15 02:18:25

This message disappeared after kernel is upgraded to 2.6.39.

Close it.
