I have the same issue after upgrade from karmic. Reboot ends with I/O error. Installation from LiveCD also doesn't start, because lucid don't recognize my hard drive.
In earlier versions (from 8.04 up to 9.10) I used grub command "boot: pci=nomsi" - without this text busybox starts only. In lucid it doesn't matter - I/O error with this command or without it.
I use Asus A8VX motherboard, Athlon 64 3800+ processor, Seagate Barracuda Sata II (ST3500418AS) hard drive and 32bit system.
Apologize for my english.
