FreeBSD 8.x install CD/DVD issue

[Florian Fuessl]

Hi,

this is a user BUG report:

Trying to install FreeBSD/amd64 8.0-RELEASE or 8.1-RC2 directly from
8.x-...-dvd1.iso or trying to run "Fixit" after booting up from
8.x-...-dvd1.iso or 8.x-...-livefs ISO-images on HP Blades results in the
following issue here:

The installation disc is not being recognized after booting up from CD/DVD;
i.e.

FreeBSD/amd64 8.0-RELEASE - sysinstall Main Menu
-> Fixit
 -> 2 CDROM/DVD
  -> Please insert a FreeBSD live filesystem CD/DVD and press return
     [OK]
  -> Unable to mount the disc. Do you want to try again?
     [YES]               [NO]

Yes shows up the last message repetitive, No reverts to "Fixit" menu.

I've tried out this procedure on different HP Blade types and have used an
external USB CD/DVD drive and HP iLO2 with integrated remote CD/DVD drive
(image) support for testing.

Booting up an installation medium of FreeBSD 7.3 this all work fine without
this issue; so I guess this problem has been introduced with the new FreeBSD
8.x kernel.

I discovered the following work-around fixing this issue:

FreeBSD/amd64 8.0-RELEASE - sysinstall Main Menu
-> Options
 -> run: Re-Scan Devices <*>

Afterwards "Fixit" and installation from CD/DVD media seems to work without
any problems, here.
