I have a SoundGraph LC16M VFD Display/IR Receiver (15c2:0036) in an 'origen ae' case and as soon as the imon kernel module is loaded I get a continuous stream of escape keystrokes making the system unusable until I blacklisted the module.
After getting some basics like network and ssh running I started some testings on the module:
loading the module with 'debug=1' revealed a continuous stream of 'intf1 decoded packet: 00 00 00 00 17 00 02 ee' in my syslog. Since everything seemd to work with natty (although I used a legacy lirc module via dkms there most of the time) I simply tested the same in my previous installation with almost the same result: The messages in syslog are the same when the module is loaded with debug, but there are no escape keystrokes present.
So I compared the imon modules source code of the 2.6.38 natty kernel and the 3.2.0 precise kernel and found next to some minor changes that several new keycodes where added in imon_panel_key_table including 0x000000001700ffeell which happens to be escape. So the module received those packets all along, but did not decoded them.
Now the question is:
Is my SoundGraph module simply broken (I have no hardware to compare with).
Is this behaviour standard for that specific device (15c2:0036) and some filter code is needed in the imon module.
Is there an error somewhere else in the code generating these data packets.
Did the manufacturer of my case (origen ae) some customizations to the SoundGraph module, causing this behaviour.
While researching this problem I stumbled accros some entries with similar headlins in some german vdr and xbmc mailing lists, but they concluded the cause due to sticking buttons. By the way: Other than the cases powerbutton (which is looped though the module), there are no buttons on the module or connected to it.
