State-Changed-Why: 
To submitter: firstly, could you please ensure that you are running
the most recent available version of the BIOS for your motherboard?
The "bad write" errors would also be seen under Windows XP and Vista.

Secondly, could you drop to the loader prompt, and give the following
commands:

set debug.acpi.block_bad_io=1
boot

and see if that changes anything?

Third, do you know if these issues have always existed, or if they used
to work with a previous FreeBSD version?  Is it possible for you to
also boot an 8.0 CD and see if the same issues exist?
