Did you patch your source with ea+acl+nfsacl-2.4.22-0.8.63.diff.gz?
vanilla -pre8 looks fine, however a strikingly similar hunk is in the
ea+acl+nfsacl patch:


@@ -923,6 +925,16 @@ call_verify(struct rpc_task *task)
                return p;
        case RPC_GARBAGE_ARGS:
                break;                  /* retry */
+       case RPC_PROG_UNAVAIL:
+               /* report requested program number*/
+               dprintk(KERN_WARNING "RPC: unknown program\n");
+               rpc_exit(task, -ENOSYS);
+               return NULL;
+       case RPC_PROC_UNAVAIL:
+               /* report requested program and procedure number, version */
+               dprintk(KERN_WARNING "RPC: unknown procedure\n");
+               rpc_exit(task, -ENOSYS);
+               return NULL;
        default:
                printk(KERN_WARNING "call_verify: server accept status: %x\n", n);
                /* Also retry */

It looks safe to just nuke this hunk from the acl patch.

NB: Always test a clean kernel tree ;-)
