Title:
  Ubiquity goes into an infinite loop on Thinkpad X130e

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  I own a Lenovo X130e (2338CT).  If I attempt to install Ubuntu 12.04
  on it, the installer goes into an infinite loop, ceasing to respond to
  user input and consuming 100% of one core, as well as slowly consuming
  additional RAM.  If I let it run for a half hour the machine goes
  completely unresponsive.  (I assume this is a side-effect of running
  out of RAM.)

  Ubiquity always fails at the same spot.  It's just after I fill out my
  account information (full name, account name, computer name, whether I
  want an encrypted home directory).  Immediately after I press
  "Continue" on that dialog, the cursor changes to the round busy clock
  cursor, and Ubiquity begins consuming 100% of CPU etc etc.  (I believe
  the next screen is the "choose your account picture / take a picture"
  wizard.)

  Barry Warsaw (and a helpful Toshio from Red Hat) examined the machine
  at PyCon and observed this behavior.  They weren't able to discover
  any more than the above.

  I have reproduced it with 12.04 daily builds over the past several
  weeks.  The most recent one I tried was the 3/28 build (sha1sum
  started with "8a235").  They all exhibit the exact same behavior.

  Varying the install options doesn't seem to affect the behavior--it
  still stops at the same spot.  It doesn't matter whether I have a
  separate home partition, or what filesystem I use for the partitions,
  or whether or not I have swap.  (I admit I haven't tried experimenting
  with different time zones and keyboard configurations.)

  My X130e is configured as following:

    * Intel Core i3-2367M
    * 4GB memory
    * OCZ Vertex 2 SSD 240GB MAX-IOPS (installed myself)
    * Bluetooth module
    * Intel Centrino Advanced-N + WiMAX 6250 (2x2 ABGN)
    * No integrated broadband adapter

  I am a reasonably sophisticated computer user and am willing to run
  experiments on the laptop upon request.
