Since kernels 3.2.0-25-generic-pae through current 3.2.0-32-generic-pae
mostly work for me as per comment #21, all I needed to add (as root) was
an /etc/pm/sleep.d/lirc_suspend (modelled on novatel_3g_suspend from the
same directory) that would "service lirc stop" on suspend and
accordingly (re)start LIRC on resume to keep usable infrared support.
No open-heart surgery really, though probably not exactly in Kansas
anymore as Joe Avg. User's self-help "comfort zone".
Some of the most recent 3.2.0-32 kernel's /var/log/syslog found in the
process might be of interest for systems where more severe issues
persist:
