Ata 1 master failure

[Casper]

  Hi,

  I just got new acer server where I installed FreeBSD:
FreeBSD www.ass.lv 5.4-RELEASE-p4 FreeBSD 5.4-RELEASE-p4 #2: Wed Jul 13 
00:57:45

and after reboot I got in dmesg:

So how I understand I have some problem with some failure... Google 
didn`t help match. So my question is does it is some sw problem or hw?
Maybe somebody can say how to debug it?

tnx,
Casper
