I need to release an update that has a chance to fix it. Jens identified
problem in his last_merge scsi patch so I will back it out.

you can try to backout it by yourself in the meantime, it's called
\*elevator-merge-fast-path\* . or you can disable it with this patch:

@@ -77,6 +77,7 @@ inline int bh_rq_in_between(struct buffe
 static int rq_mergeable(struct request *req, struct buffer_head *bh,
 			request_queue_t *q, int rw, int count, int max_sectors)
 {
+	return 0;
 	if (q->head_active && !q->plugged) {
 		struct request *next;
 		next = blkdev_entry_next_request(&q->queue_head);

Hope this helps.
