No disks found

Hi,

On one of my systems, I get the message "no disks found" during the
installation of 8-current.
During boot it detects the disk controller correctly (atapci0: <nVidia
nForce MCP55 SATA300 controller), but not any of the disks.


Tried with both a regular SATA harddisk, as well as an MTRON SSD.
When I connect the SSD, it does generate the following messages:

==
unknown: timeout waiting to issue command
unknown: error issuing ATA_IDENTIFY command
==

So apparently some communication with the disk does happen.


System is a Tyan barebone:

Under 7.0 the same system works fine.
Problem occurs with both the December snapshot of 8-current, as well as
with the current code in CVS (built an ISO on a different system using
"make release").

On the FreeBSD forum someone else is reporting the same problem:

Anyone got a solution?
