 Have you isolated it to Seagates only? our problematic rackables have
 seagate drives, but I don't have any other mfr drives (maxtor, ibm) to
 test it with.

I have a possible problem with the Tyan S2518GN and a Maxtor 80GB
disk.  Didn't have time to play with it--I just shoved in a Promise
ATA/133 controller and now the disk is really fast.  I haven't tried
updating the BIOS from the default v106 yet.

 No, that's from the Alan Cox posting I mentioned.  I'm afraid didn't
 have any drives of other brands handy so I gave up on the IDE
 interface and went all-SCSI.  Here's another report of the problem,
 but also with a Seagate disk:

   
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=577071+0+archive/2002/freebsd-hackers/20020224.freebsd-hackers

I'll add it to the doc file.

One of our other admins took some time to chit-chat with rackable about
their situation.  Apparently that and some other weird problems are
firmware bugs that Tyan is working on firmware to fix.  Not sure if Intel
plans to do the same changes once they've been hashed out by Tyan and
other ServerWorks users. (Intel now owns ServerWorks I believe...)

 On the SCB2 Intel has a big warning in the manual to not use that IDE
  interface for system disks. I don't see it in the STL2 manual so I guess
  they learned their lesson later on.

 We don't have any SCB2 systems here, but its specs say it has a
 Promise controller, rather than the ServerWorks chip on our STL2.

It still has the OSB4 IDE interface exposed on the board. The SR1200
chassis uses the ATA RAID connectors though, and the build manuals say to
use the RAID channels, yadda yadda.  The CDROM uses the secondary channel
off the OSB4 I think, I'd have to check the dmesg again.  The ATA RAID is
UDMA/100 so it's a huge improvement either way :)

 The Serverworks chipsets max out at ATA/33.  Not very fast.

That's hardly the worst of it.  The ServerWorks OSB4 ATA controller
has been known to cause data corruption with Seagate drives.  

I've just had a very frustrating experience with this problem on an
Intel STL2-based 4.6-PRERELEASE system which experienced segfaults
and file system corruption.  We tested the memory, checked the PSU,
heat in the system, replaced the IDE cable, replaced the drive
(unfortunately with another Seagate!) before I heard about this
issue.  My testing showed that the problem only occurred while
writing to disk using UltraDMA.

This post on the Linux kernel list gives further details:

The most reliable machine I ever had (and still have) is
a VAXstation 3100, running NetBSD.  That's rather off-topic
wrt your question though but it's my opinion that whatever
off-the-shelf PC hardware you buy these days, you'll never
reach the robustness of the well designed and engineered
minis and workstations from about 10-15 years ago.

I was going to go to the meeting too, I have a long list of these. :) I'm
mainly lookigin at server-class stuff here.

In somewhat chronological order ...

1)  At eGroups/Y!Groups we used Intel L440GX+ motherboards. These are now
(sadly) discontinued, but supported slotted P2 and P3 CPUs. Very solid if
you used approved memory. (we had a famous incident with a hardware vendor
using non-spec memory...)  Hard disks where the IBM Deskstars before they
went to crap.  The kernels had mbuf(cluster)s jacked up and ran 3.2-STABLE
of some generation.  After the merger they converted over to the standard
Y! kernel-from-hell.

2)  At my current employer we largely split into to machine types:
  a) The replicatable servers (webs  mid level logic) are on tyan S2510
 and S2518 in the rackable systems half-1U box.  They use the
 ServerWorks chipset with the busted ATA controller, so make sure you
 use SCSI or get the ATA RAID version to avoid it.
  b) HP Netservers of the last two generations, largely LPr, LP1000r and
 LP2000r. The HPs are pretty well built, although their onboard
 management card is half-useless with any decent terminal server. They
 do support IPMI so you can (largely) avoid having to use that thing.

  Most machines are dual proc 866 or 900MHz P3 with 1-2 GB RAM. They
  usually run linnex but we have a few bsd boxes sprinkled about.

3) I demoed a new Intel SCB2 motherboard in their SR1200 chassis a month
or so ago. Very, very nice machine.  Ran really fast with the onboard
fasttrack ATA RAID (also available in SCSI).  Also supports the full range
of IPMI monitoring features and even has rj45 serial connections.

4) I have a dual AMD 1400 demo coming... eventually.

In summary:

. The Intel motherboards are quite good. You get what you pay for. They
usually have onboard everything, including dual fxp's nowadays.  But they
have the ServerWorks curse.
. Tyan makes some interesting stuff, but as with all ServerWorks based
stuff, stay far, far away from the base ATA33 controller. Even the cheap
FastTrack ATA RAID they put on is ATA100 and is plenty fast (and
supported!)
. As soon as I get my hands on the AMD stuff I'll consider a
recommendation. :)
