Subject: unable to set udma >= 3 on ich5 on 2.6.11
Date: Mon, 20 Jun 2005 09:06:06 -0300	[thread overview]
Message-ID: <564d96fb05062005064283caaf@mail.gmail.com> (raw)

I have a intel 865glc motherboard. lspci shows

0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100
Storage Controller (rev 02)
0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 Storage
Controller (rev 02)

from the above message and from the fact that the line
"combined mode detected" does NOT appears in dmesg I assume that I am
not I am not in combined mode. Right?

In the bios config the disk (a quantum lct 30GB) is listed as having a 80
connector cable attached and working at udma5.

Unfortunately hdparm shows the drive at udma2:
UDMA modes: udma0 udma1 *udma2 udma3 udma4 udma5

and using -X69 does not change it.

I see that someone had a similar problem in freebsd:
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/hackers/2003-12/0022.html

Maybe it is the same problem (80 conductors cable not detected by the driver).

Does someone has a suggestion before I start adding prinks to piix.c?  :)

Thanks,
Rafael Ávila de Espíndola
