xfs corruptions

Hello,

I'm presently debugging the error handler of the MPT fusion driver and
therefore causing errors on the disk (Infortrend scsi hardware raids).
When I later on try to delete files and directories having been created
before and during the failures, "rm -fr" simply says directory not empty.
No message in dmesg about it, but xfs_repair reports errors, see below.
Once xfs_repair has done its jobs, removing these directories works fine.
But this shouldn't happen, should it? This is with 2.6.26

- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...

Phase 5 - rebuild AG headers and trees...
- reset superblock...
Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- traversing filesystem ...
- traversal finished ...
- moving disconnected inodes to lost+found ...

Thanks,
