*Description :
I don't know how exactly to descibe this problem,
but dbench starts reporting errors under some circumstances.
AFAIK, this is related to the xfs-cmds version used
to mkfs/mount/repair (etc.) the file system.
Using the same kernel, dbench would run fine when
1.0.2 version of the xfs-cmds is used, but reports
errors when 1.0.4 version (as of today) of xfs-cmds is used.

Here's Nathan's suggestion:

--------
when you do a fresh mkfs, then run xfs_logprint, does it just
say:

# /usr/sbin/xfs_logprint /dev/hda7 
xfs_logprint:
    data device: 0x307
    log device: 0x307 daddr: 1020128 length: 9600

xfs_logprint: skipped 9600 zeroed blocks
xfs_logprint: totally zeroed log
xfs_logprint: physical end of log
============================================================================
xfs_logprint: logical end of log
============================================================================
#

(thats what it should say, anyway).
--------------

Chait, can you try this on your system?

ananth.
