Sata problem

[Matthew Dillon]

:Hi,
:
:I'm trying to install dragonflybsd on this machine: 
:http://www.supermicro.com/products/motherboard/Xeon1333/5400/X7DWT.cfm
:
:Since the machine does not have a CD-ROM, I'm netbooting it using the
:configuration found on the CD from a linux server (nfs root + dhcp).
:
:There seems to be some problem with the SATA disk:

:I'm attaching the full dmesg.

    That's really odd.   The raw disk should be writable.  I don't
    know, I've never seen that particular error before.
