XFS-1.1+DEBUG+dbench = panic

["Tang Lingbo (Allan)" <atang@xxxxxxxxxxxxxxxxxxxx>]

Hi,

If I run dbench 50 after enabling the 'CONFIG_XFS_DEBUG' and
 'CONFIG_XFS_VNODE_TRACING' in XFS-1.1, the system will report
Kernel panic. ( patched kdb) The partition is a new one and no other
operations and this panic can be reproduced.

But if disable these flags, panic seems disappeared.
Is there any issues in debug routines?
