Greetings,
I have been troubleshooting a problem for over a year now, and to make a
long story short, I think the sata_sil driver has a bug during writing when
there are multiple cards that are using different models of SiI chips in the
system.
I will be watching the list, although cc'ing me over email will be useful
for speeding up replies.
Longer version:
I've been having problems with my Linux server corrupting data. Not just a
little - it can't copy a 700 meg ISO file and end up with the same checksum
(and usually corrupts the filesystem in the process).
Hardware:
Asus A7N8X-Deluxe motherboard. This has 2 parallel IDE connectors, each
with a 40 gig IDE HD hanging off it, and 2 SATA connectors (driven by a SiI
3112 chip) with (right now) 1 300G SATA HD and 1 250G SATA HD. All of these
facts are important.
On my PCI bus, I have a SiI 3114A card with 3 more 300G SATA HDs. It should
be noted that only drives on the PCI card have corruption. Neither the
parallel IDE HDs, nor the SATA drives on the motherboard experience the
problem. I have also tried replacing this card, which did not fix the
problem. Also, placing the same drive on the add-on card has corruption,
the same drive, cable, power, etc. on the motherboard works fine.
I've already swapped motherboards, CPU, and RAM.
Booting to a Knoppix 5.1 CD shows the same problems.
Reading is fine (i.e. I can read the same file 50 times and get the same
md5sum). Writing causes the corruption.
The corruption happens no matter what filesystem I try (ext2, ext3, reiser,
xfs). (This does mean I've reformatted, etc. several times, so its not a
metadata problem)
This happens with at least 3 different drives (the 300 and the 250,
different manufacturers), with different SATA data cables, power supplies,
power cables, etc.
Now, here's the kicker. Booting to an OpenBSD kernel, and using one of the
300G drives off the 3114A card (the one that show corruption under Linux)
works fine.
This happens with the Knoppix 5.1 kernel (2.6.19), my own compiled 2.6.20.3,
and Debian kernel 2.6.18-4-k7.
