Further investigation indicates that the problem occurs in fs/xfs/xfs_dmapi.c,
xfs_dm_send_data_event(), in this code (line 183):

#ifdef DM_FLAGS_IALLOCSEM_WR
                if (flags & DM_FLAGS_IALLOCSEM_WR)
                        down_write(&inode->i_alloc_sem);
#endif

The down_write() hangs (shown by adding printk's before and after this 
statement).
