Subject: Si3112 S-ATA bug preventing use of udma5.
Date: Fri, 23 Apr 2004 16:02:28 -0600 (MDT) [thread overview]
Message-ID: <42822.68.144.162.3.1082757748.squirrel@webmail.rty.ca> (raw)
In 2.6.5 (not sure about other versions) there is a bug/problem in the
drivers/ide/pci/siimage.c driver. I have only tested this with my Si3112
chipset on an ASUS A7N8X-Deluxe mobo. I did not discover this fix, and
I'll post a url below to the original source. No idea if this has been
fixed/looked at already, but it definitely needs to be resolved.
hdparm -t speed without fix: 16mb/s
hdparm -t speed with fix: 55mb/s

Incase the link is down/broken, to fix the bug change line 269 of
drivers/ide/pci/siimage.c from:
u32 speedt = 0;
to:
u16 speedt = 0;
Regards,
Brenden
