SiI 3114 woes

[Mars G. Miro]

Yo list/Soren!

 Has anybody successfully installed FreeBSD on the dual-Opteron TYAN
ThunderK8W S2885 ( http://www.tyan.com/products/html/thunderk8w.html )
 using the onboard SiI 3114 SATA controller? This mobo is supposedly
supported:
http://www.freebsd.org/cgi/query-pr.cgi?pr=80857

 But I have never been able to successfully install
FreeBSD({5.3/5.4/6.0Beta3/4} amd64/i386) on it, using SATA.
 
In my last attempt at installing 6.0Beta4 AMD64 on it, I get:

 ad4: FAILURE - WRITE_DMA status=51<READY,DSC,ERROR> error=4<ABORTED>
LBA=105819039
 g_vfs_done():ad4s1e[WRITE(offset=23695114240, length=2048)]error = 5

  at the debugging console 
 
 and

 Some months ago, I did successfully install FreeBSD 5.4/amd64 on it,
using PATA IDE drives, and no problems whatsoever, so I think this has
something to do w/ the SiI 3114 driver.

 Any help is much appreciated.

 I do apologize for cross-posting but this concerns -stable and -amd64.

 Thanks!
