Bug description:
  After upgrading from 3.8.0-23 to kernel 3.8.0-24 currently in
  -proposed, wireless WPA enterprise authentication stopped working. I
  am having issues now which very much resembles the problems in bug
  1104476 (although I do use a certficate).

  Here's some output from syslog during connection attempt:

  The connection uses TTLS/MSCHAPv2 auth with certificate.

  Booting older 3.8.0-23 kernel makes it work fine again, so something
  has regressed.

  It's been several years and Ubuntu releases since I've had any
  problems connecting to this network (at work).
