Starting hald causes ILLEGAL REQUEST messages for acd0

[Maxim Khitrov]

Greetings,

I'm running FreeBSD 7.0-BETA3 (full uname below) and have just run
into a problem trying to get xorg to work. The short description is
this - I'm running this system using VMWare Workstation 6, when I
start hald this is what happens:

Fri Nov 30 19:57:53 EST 2007

At this point the system reboots. I've tested this using my own
kernel, and the generic one. No difference. The only ata-related
devices I have in my kernel are "device ata" and "device atapicd". Any
ideas on what is causing this?
