N/A (can't boot install dvd)
>Description:
When trying to install 8.1-RELEASE using the dvd install media,
the boot hangs when geom label is tasting the disk. See this
screenshot when booting with kern.geom.label.debug=2 and
kern.geom.debugflags=7:

http://www.sics.se/~bengta/FBSD/IMG_1703.JPG

The dmesg from a 7.3-REL boot which works fine is attached.

The disk contains a factory-installed Windows XP and a recovery
partition (which I intend to wipe out).  The mbr partitioning looks
like this:

******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=77520 heads=16 sectors/track=63 (1008 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=77520 heads=16 sectors/track=63 (1008 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 12 (0x0c),(DOS or Windows 95 with 32 bit FAT (LBA))
    start 63, size 69536817 (33953 Meg), flag 80 (active)
        beg: cyl 0/ head 1/ sector 1;
        end: cyl 1023/ head 239/ sector 63
The data for partition 2 is:
sysid 18 (0x12),(Compaq diagnostics)
    start 69536880, size 8603280 (4200 Meg), flag 0
        beg: cyl 1023/ head 0/ sector 1;
        end: cyl 1023/ head 239/ sector 63
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>

>How-To-Repeat:
Just boot the install media with this disk.
>Fix:
I guess that wiping the mbr will fix this, but I will wait with
doing that for further debugging.  Is there anything more I can
do in order to find the bug?  It is possible to get a crash dump?
