I have a system with a Tyan S2882 mother board that has a Silicon Image
Si3114 SATA controller that I would like to use one of the "blacklisted"
Seagate drives on. As has been discussed in this mailing list, when one
uses the current driver performance is poor on this combination (I
see around 14MB/s using hdparm's buffered read test--Bonnie++ confirms
that).
I was hunting around to see if there might be a better driver, and came
across this note in the Release notes for the:
SiI SATARaid Linux device driver ver 1.0.0.20 Release
Both the Tyan support download driver and the one from SiliconImage
have the following "Limitation" listed:
3. Mod15Write fix for Seagate Drives (for chip-set versions 3112 1.21 or older)
It seems that this driver may treat the 3114 and the 3112 the same way, and
that at least in the 3112 code the Seagate problem may not exist on newer
versions of the SI chip. Lspci thinks that I have a Rev.2 chip/firmware:
04:05.0 Unknown mass storage controller: Silicon Image, Inc. SiI 3114
[SATALink/SATARaid] Serial ATA Controller (rev 02)
The SI firmware version that my SI chip is running is 5.0.48.
My question is--is it possible that my ST3120026AS Seagate drive might
work without the "blacklisting"? Should I try it? If so, what is a
good test--will it lock up, or corrupt data?
If not with the current driver, then is there a new driver that
is coming down the pipe that will fix this in the reasonably near term?
Thank you,
