Re: XFS Bug null pointer dereference in xfs_free_ag_extent

[kernel <linux@idccenter.cn>]

My hardware is dell 6650 and a FLX380 SAN storage,connected with a

The another machine is dell 2850 with the same card.
I can reproduce this error with bonnie++ easily.Espacially bonnie++ 
delete small files and small directories.
