The HT1000 is only 1 of the Opteron chipsets available from Tyan, and
it's only available on their 1 socket boards (the Tomcats). The dual-
and quad- socket boards either use AMD or AMD+nVidia chipsets (Socket
939/940), or nVidia chipsets (Socket AM2). Out of their entire lineup,
the HT1000 makes up maybe 10% of the chipsets used by Tyan.

I'd hardly call that a "black eye". And it's only the onboard SATA
controller that has issues. Pop in a proper RAID controller, and it's no
longer an issue.

Hate to sound like a broken record but that's exactly what I did and I
ran into the same nasty data corruption problem on that controller, too.
That was a little frustrating.

atapci0@pci0:2:3:0: class=0x010000 card=0x11ab11ab chip=0x608111ab
rev=0x09 hdr=0x00
vendor = 'Marvell Semiconductor (Was: Galileo Technology Ltd)'
device = 'MV88SX6081 8-port SATA II PCI-X Controller'
class = mass storage
subclass = SCSI

I don't want a hardware RAID or a "software RAID" controller, I just
want normal SATA ports with no RAID so I can use ZFS :)

I find myself much preferring ZFS to any other data management solution
I have ever used, including 3ware hardware RAID which was my previous
favorite.

Another thing I haven't tried yet is a 3ware 9500 series PCI-X
controller in my HT1000 board's PCI-X slot to see if that's also broken
or if it's just a PCI-X + ata(4) specific problem.

I'll reply with the result of that when I get to trying it out.

Someone was complaining 2 years ago that they didn't
have hardware to do the work. Is the FreeBSD project
really so poorly funded that they can't get their
hands on a $150 motherboard for 2 years?

Ever considered sending one in? :)

I am considering it. Are any reputable FreeBSD developers interested in
this problem that could benefit from having the problematic hardware in
their posession?

I'm in the middle of retiring nearly a dozen supermicro socket AM2 boards with
this chipset. With the SATA controllers in native SATA mode the disks get
scribbled on horribly. With the SATA controllers in legacy mode FreeBSD
detects them as ATA/33 but they seem to hold up a bit better. Under heavy
I/O load they will stay up for about a week before panicing, although once
they do panic they double panic and hang solid. I thought I was going dodge
swapping platforms by installing 3ware 9550 RAID controllers but I all I
managed to do was reduce the panic rate to about once per month per box, so
there are gremlins that affect more than the onboard SATA I'm afraid. I've
attempted to work with at least one FreeBSD developer on a fix, but the
inability of the boxes to complete a panic, let alone write a crash dump has
made troubleshooting them incredibly painful. (Sometimes they don't even
manage to get the entire first line of the panic string on the console) The
fact that they will stand up for days under heavy I/O load doesn't help
either. Intermittant problems suck.
