Some how I found in /etc/modprobe.d/options this 2 lines =

Today after renting a dvd movie had similar issue as this bugs refers to ,
playing dvd movie with any player my cpu goes really high , playing the movie
looks as if I am playing the movie in slow motion, reading the files
I kind solved my problem temporally:
I added Hardy repositories and installed only 2.6.24-21-generic.
I started with that kernel and my sd* became hd* and all the
information/tune-up of hdparm
works just fine.
NOW:
/dev/hda:
Timing cached reads: 918 MB in 2.00 seconds = 458.69 MB/sec
Timin
I updated from 2.6.24 to 2.6.27 (From Hardy to Intrepid) and my drives changed
from hd* to sd*.
Since that change, all drives are very slow (HDD and DVD). For burning a 2Gb
disk it took about an hour!
I have read many forums and I have tried several setups, specially with kernel
options and in
The suggestions of "alih" few posts back resulted in slow HDD
performance for me. Buffered reads went from 19MB/s to 3MB/s. I'm using
a Via82Cxxx chipset, the drivers for which seem to have been removed
from (at least) Hardy.

If it is intentional that libata has less functionality (and removing
