Had this problem on a dual P3/733, 256MB RAM, Compaq AP550 workstation with Intel reference board.
I upgraded from -386 to -generic by installing the linux-kernel-generic package and changing my grub config. The update-initramfs method worked for me as well. -- "-generic" kernel doesn't boot after upgrade to Edgy prerelease (but -386 does) https://launchpad.net/bugs/67256 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
