This boot failure bug appears to be similar to Bug #609845.
A curious feature of my bug is that when you comment out "quiet splash" in /etc/default/grub and then "sudo update-grub", the boot failure appears to be resolved.
I will report back after 3 months of verbose booting as indicated above, unless I upgrade to 11.04 Natty Narwhal.
In the interim, I would suggest that the 9 victims of Bug #609845 try verbose booting. If the problem goes away for all 9, then we can use that to refine our debugging efforts.
Wiki article https:/ /wiki.ubuntu. com/Plymouth# Debugging requires entering the Grub2 boot menu. As indicated previously (Bug #425979), a Grub2 bug makes this impossible.
