           Summary: filesystem corruption while running bonnie
           Product: File System
           Version: 2.5
     KernelVersion: 2.6.28.1
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext3
        AssignedTo: fs_ext3@...nel-bugs.osdl.org
        ReportedBy: folkert@...heusden.com

mkdir /mnt/tmp /tmp/tmp ; mount -t tmpfs /dev/null /mnt
chown folkert /mnt/tmp /tmp/tmp

and then in parallel:
while [ 1 ] ; do bonnie++ -d /tmp/tmp -s 128 -r 64 -x 1 -u folkert ; done
while [ 1 ] ; do bonnie++ -d /mnt/tmp -s 128 -r 64 -x 1 -u folkert ; done

then after say 15 minutes i run the reboot command (normal via init) during the
fsck (I always do a touch /forcefsck) I get:
fsck 1.41.3 (12-Oct-2008)
/dev/mapper/VGODR-tmp contains a file system with errors, check forced.
