Sorry, i cant boot into BSD. Description:

- 2x Maxtor 200GB S-ATA 150 Harddisks
- Dawicontrol DC150 S-ATA 150 Raid Controller (Raid 1)
- Asus P3B-F Mainboard with P3-450
- Terratec ad1816 Soundcard
- Allied Tele Sync 1GBit Ethernetcard 
>Description:
I installed FreeBSD 6.0 on my system.
Everything works fine but when it comes to extract the "ports" to /usr the system freezes.
I tried to not install the "ports" collection and the installation succeeded. So I tried to install this collection later via sysinstall from different media, FTP, CD etc. but always crashed.

Then I cancelled it and copied about 5GB of data via Samba on the server but after a while it freezes and says "ATA2: DISCONNECT REQUESTED".

I searched the internet and bsdforen.de (which is the german bsd forum) and im not alone with this problem and not only my Controller is "affected".

All hardware is very new. I tried to install FreeBSD 5.4 but it does net initialize my S-ATA RAID Controller. Its a Dawicontrol DC-150.

Sometimes it hangs during the installation while formatting and creating the partitions.
>How-To-Repeat:
Install the ports, copy many files so HDD is busy.
