What described in 343371 was another problem and I had that one too...

I'm not too lucky...

I resolved it adding my hd (WDC WD3200BEVT-22ZCT0) in the NCQ blacklist
in drivers/ata/libata-core.c and now I can read very big files from the disk
without any problem...

However, the visible slowdown using cfq on some devices remain, with
high IO wait and high elapsed (from the start to the end of the write).
