Hi all. This does indeed occur on i386 also. I had a drive die in a 
machine this past week and replaced it with two brand new Seagate 80GB 
SATA 300 drives to do mirroring, but 6.1-RELEASE only detects one of the 
drives (and only the one on the primary SATA channel even if I switch 
them around).

Upon finding this PR, I tried 6.0-RELEASE and it detected both drives on 
the install, so I went ahead and installed 6.0 to use until there is a 
fix since this is a production workstation. Unfortunately, I forgot that 
I was running 6.1-PRERELEASE on the previous install because none of the 
controllers on my board (MSI K8NGM2 - nForce4) are detected in 6.0, and 
instead run as "GENERIC" at UDMA33.

I don't have the latest BIOS since it requires Windows to update, but 
the summary for all updates show mainly CPU things...nothing related to 

I'm trying to decide if I should use 6.0 with the "GENERIC" controller 
and reduced speeds since it needs to be operational, or try the nve 
patches to fix the onboard LAN so I can free up a PCI slot and then put 
in a known working SATA controller that would be recognized and at full 
speeds. Not meant as pressure in any to the developers, but I'm 
wondering if you guys think it will be a while before this is fixed so I 
can make an informed decision on hardware purchases or not and get this 
machine back up.

Thanks in advance!
