Further information on this bug.
The installer system hang was originally encountered with
the HP NetRAID controller.
I also tried the following other models of this controller and
experienced the same system hang with both of them:
NetRAID 1Si - HP Part No. D2140-63004
NetRAID 1M - HP Part No. P3410-60001
I also tried an Adaptec 2940 (non-RAID) adapter and with
it the installer ran just fine. Based on this, I reinstalled the
HP NetRAID (original) controller and changed the configuration
so that each hard-drive was a logical drive (no RAID 1 or 5)
to simulate the non-RAID configuration of the 2940. Even
with this simplified configuration the installer still hung.
