*Description :
OK, so this one is repeatable now, and it looks like an
interraction between the ramdisk driver and XFS.

        2 way SMP 1400 with 1Gb memory, 
        SCSI disk. 
        t-o-t kernel, kio _not_ enabled.
        
setup:

        mkfs -t xfs -f /dev/sdc5

==========================

Changing the title on this one, it is not an XFS problem at
all, rather a general linux locking bug. Not sure we should
keep a PV on this one or not....
