I downloaded the daily built i386 businesscard iso from http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/i386/iso-cd/debian-testing-i386-businesscard.iso 10 minutes ago (and also yesterday around 4pm EST, with the same results), and downloaded http://people.debian.org/~joeyh/d-i/images/daily/hd-media/boot.img.gz at the same time.
I checked the md5 sums, they were correct. Then I configured a USB key for installation:
zcat boot.img.gz | dd of=/dev/sdb
mount /dev/sdb /mnt/
cp debian-testing-i386-businesscard.iso /mnt/
umount /mnt
I booted off the USB key.
It gets to the point where it is "Loading additional components", then it says:
There was a problem reading data from the CD-ROM. Please make sure it is in the drive. If retrying does not work, you should check the integrity of your CD-ROM.
I've tried rewriting the USB key numerous times and checking md5 sums of the iso on the key, and I don't believe there is a problem with the key.
Doing the same thing, but using the debian-testing-i386-netinst.iso file instead works fine.
So, I suspect there is a problem with the businesscard iso.
Please CC me in replies.
Thanks.
