$ lsb_release -rd
Description: Ubuntu lucid (development branch)
Release: 10.04

$ uname -a: Linux mitch-lucid 2.6.32-20-generic #29-Ubuntu SMP Fri Apr 9 20:35:55 UTC 2010 i686 GNU/Linux

This problem was first noticed in -19 kernel revision. In -19 kernel this laptop failed to boot on approx. 1 out of 20 boots. After updating to the -20 kernel today this laptop fails to boot in approx. 9 out of 10 attempts.
The laptop hangs at "new USB bus registered, assigned new bus number r3".

I noticed that there are multiple bug reports for this issue (e.g. bug #528688). I have filed this separate bug as my laptop hardware appears to be different.

I have also attached the output of: $ sudo lshw>hardware.txt
