This is really driving me mad. <br>
<br>
I'm doing a fresh install of 12.04LTS with a 'sudo apt-get
upgrade' everything. At that point I install lirc and get it
working fine. I have the right hardware.conf and I can see
all the key presses working fine using irw. I'm using a
Hauppauge PVR-150 card and the IR receiver/remote that comes
with that. Everything is fine. All is good with the world. I
can issue sudo service lirc restart and it works as
expected. <br>
<br>
Then randomly after a reboot everything stops. irw simply
says connect: No such file or directory. If I try to do
anything with lirc, either 'sudo service lirc stop' or 'sudo
apt-get purge lirc' then the session hangs. Nothing. Even
reboots start to hang. All I get is a message on the screen
saying 'acpid: exiting Checking for running
unattended-upgrades:'. <br>
<br>
If I check the dmesg log I see a bunch of messages along the
lines of:<br>

I have tried everything I can think of. I've had remotes
working fine on this machine before. For about 4 years this
was my MythTV backend. I decided to upgrade a week ago and
have been solidly stuck on this issue. I would greatly welcome
any help anyone has. <br>
<br>
Thanks, Paul</span><br>

What driver are you using for lirc? <br>
Can you post your /etc/lirc/hardware.conf script?<br>
When you've restarted your system, is lirc running - what does 'ps
-ef | grep lirc' give?<br>
Could you put the output of 'dmesg | grep -v IRQ | grep
'lirc\|rc\|IR' -C3'
</div>

Before upgrading to 12.04 this system was rock solid and the remote control worked perfectly. I'm almost tempted to roll back to version 11.</div>
<div><br></div><div>When I posted this I removed lirc due to the issues I was experienced. As you very kindly replied I reinstalled it. As usual it was working fine in that I could get irw working and recognising keypresses. Then as usual after several reboots it suddenly stops working with the usual symptoms of hanging whenever I try to do anything with lirc or try and shutdown the machine. I've tried as best to answer your questions. Usually to test lirc works I type:</div>
