That's stalled waiting on the inode cluster buffer lock. That implies
that the inode lcuser is already being written out and the inode has
been redirtied during writeout.
Does the kernel you are testing have the "flush inodes in ascending
inode number order" patches applied? If so, can you remove that
patch and see if the problem goes away?
Cheers,
Dave.
