[Bug 110636] Re: hdparm - cannot set dma on IDE hard drive that works via pata

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
 /etc/initramfs-tools/modules
I also followed "alih" recommendation without any success:

BEFORE:

/dev/sda:
 Timing cached reads:   858 MB in  2.00 seconds = 428.97 MB/sec
 Timing buffered disk reads:   64 MB in  3.02 seconds =  21.19 MB/sec

AFTER:

/dev/sda:
 Timing cached reads:   646 MB in  2.00 seconds = 322.90 MB/sec
 Timing buffered disk reads:   64 MB in  3.03 seconds =  21.12 MB/sec

Is there any way to change my drives to be hd* again?

Thank you
