Asus A8N-SLI problems

[Roberto de Iriarte]

Dear developers. 

I have found an unsolvable problem installing FreeBSD on an Asus A8N-SLI  
mainboard. 

I've tried 

6.1-RELEASE i386
7.0-i386 (Snapshot from 07/2006)
7.0-amd64 (Snapshot from 07/2006) 

and found the very same problem, the SATA Harddisks are detected, however, 
the boot process hangs just after enumerating them. Booting with ACPI 
disabled does not help either. Booting with the DEBUG option shows the same 
effect, the boot process hangs after GEOM tries to determine if the disk has 
a RAID signature. 

Hardware configuration
Asus A8N-SLI
Bios revision 014 (Latest)
2 GB SDRAM PC3200 (2x1GB)
AMD64 3700+ processor.
ATA DVD-RW PIONEER DVD-RW DVR-109
SATA WDC WD740GD-00FLA2 on port 0
SATA Seagate ST3120827AS on port 1
ATI Radeon X700 PciE video card. 

I don't know if there is a bug with FreeBSD, thus i have not filled a bug 
report (should i?) but i suspect something is broken with the A8N-SLI as 
i've replaced it with a Tyan Tomcat K8E that works perfectly. (And has no 
high-rpm chipset fan, as a bonus) 

Regards
