Public bug reported:
I tried to install the karmic beta release to an ATAoverEthernet disk. As the
installer doesn't have direct support for this I booted the live system and
manually did:
modprobe aoe
cd /dev
ln -s etherd/e0.0 sda
ln -s etherd/e0.0p1 sda1
Then I started the installer and I am able to select the AoE disk (it's
correctly listetd as /dev/etherd/e0.0 but, the sda symlinks are necessary, i
don't see the disk without them). Installation runs fine but at 80% it just
hangs at "Scanning the CD-ROM...".
I found the following error in dmesg output:
