This appears to be an internal problem with creating the directory
"/proc/fs/ldiskfs/cciss/c0d0p6" because the "cciss" part of the
tree does not yet exist and the "c0d0p6" subdirectory create fails.

As a temporary workaround, can you please try modifying the ldiskfs code:

        sbi->s_dev_proc = proc_mkdir(sb->s_id, proc_root_ext3);
        if (sbi->s_dev_proc == NULL) {
                printk(KERN_ERR "EXT3-fs: Unable to create %s\n", sb->s_id);
+		/* Don't fail mounting if the /proc file can't be created
                sb->s_fs_info = NULL;
                kfree(sbi);
                return -ENOMEM;
+		*/
        }


It looks (though I'm not 100% sure) that the rest of the mballoc code
will deal with s_dev_proc == NULL properly.

Cheers, Andreas
