Bug Description
BUG: unable to handle kernel NULL pointer dereference
My philips MCE USB receiver (mceusb device) does not work with Lirc. System is ubuntu 12.04-mini.
lsusb
Bus 003 Device 002: ID 0471:060c Philips (or NXP) Consumer Infrared Transceiver (HP)
Running irw does nothing, running it a second time gives "Connection refused".
xbmc@Media-PC:~$ irw
xbmc@Media-PC:~$ irw
connect: Connection refused
After the first irw, lirc is already 'hanging'! Restarting the lirc service at this point will hang the terminal which you will try to run it from.
Sudo dpkg-reconfigure lirc will also hang the terminal plus give a dpkg-configure -a error on next boot.
On reboot the system will hang as well, only option being REISUB.
syslog after running irw twice:
