You don't seem to realise that this is a BUG (somewhere, could even be in the generic mapping functions)! blk_rq_map_sg() must never map a request to more entries that rq->nr_segments, that's just very wrong. That's why I'm suspecting the recent pcidma changes. Just a feeling, I have not looked at them. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | |||||||||
