I haven't seen a particular commit to 2.0-RELEASE related to ACPI or PCI
in that time window, so if someone else comes up with an idea why recent
Release ISO hangs your computer, but not the July release, you may have
to binary search the commit by looking at the following website:

  http://repo.or.cz/?p=dragonfly.git;a=log;h=refs/heads/DragonFly_RELEASE_2_0

and the commits which touched under /sys/{contrib,dev,net*} are:

I'm not sure how much delay there is between the commit and the ISO image is
finished, so you may want to try the date between two commits.

You can find ISO snapshots for 2.0-RELEASE at some of our mirror sites,
such as:
  http://pub.allbsd.org/DragonFly/snapshots/i386/ISO-IMAGES/

Cheers.
