Hi Jarod - you are correct, the script was installed when I took the
log, a leftover of trying to find a workaround. Sorry for the clutter on
my previous post, please disregard it.


I removed the script, same result (this is where I got started, actually):

... See the "caught signal... lircd" line in the resume part, and see
the "BUG" line right after, which I guess is related.


The same happens with both kernels: 2.6.38-10, and 2.6.39-3

Title:
  Lirc mceusb resume problem

Status in “lirc” package in Ubuntu:
  New

Bug description:
  Binary package hint: lirc

  Dear All

  I've XBMC 10.1 running on Ubuntu 11.04. I'm using a mceusb dongle

  I've installed lirc and my harmony remote works fine.

  The main problem is after the suspend the remote is not able to resume
  the pc and if I manually do it lirc is not working anymore.

  with ubuntu 10.10 the problem was solved using the following howto:

  http://wiki.xbmc.org/?title=Automati..._resume_script

  but it looks like it's not working on 11.04.

  I've tried to:

  1. stop lirc
  2. rmmod --force lirc_dev
  3. rmmod --force mceusb
  but it looks like I ca't "ERROR resource busy" or sometime the command hang.

  Thank you

  L.
