I recently installed (not an upgrade) R5F1 to my main KnoppMyth machine (Chaintech 7NIF2 motherboard, Athlon 2400+ processor, 1GB RAM, PVR-250 and PVR-350), replacing the R5C7 version that I'd been running.
After the install my Hauppauge remote (the gray R808) was very slow to respond, and eventually shut down altogether. This is after repeated reboots, battery changes, rerunning lirc-reconfig.sh, and adjusting /etc/lirc/lircd.conf .
I get the following errors in /var/log/messages
Code: May 11 15:40:56 mbe kernel: i2c IR (Hauppauge): unknown key: key=0x25 raw=0x17e5
down=1 tkoster pointed out to me elsewhere that "...apparently this is a common problem as of late due to a conflict between lirc_i2c and ir_kbd_i2c, the latter of which is build into the last few kernels." He also provided the following link describing the problem and how to solve it, but only if you're using Gentoo: http://ivtvdriver.org/pipermail/ivtv-us ... 06196.htmlThe following instructions look more generic but I'm still not sure how to adjust KnoppMyth accordingly: http://linuxtv.org/v4lwiki/index.php/Re ... with_lircdI'd appreciate help with how to properly remove the lirc_i2c module and to try to use the remote with ir_kbd_i2c . Thanks.[/code]

I've been thinking on this and was wondering if a simpler solution might be to rebuild the kernel without the ir_kbd_i2c. It would depend on whether there is some other component essential to knoppmyth that depended on ir_kbd_i2c.

I've been working on this off and on now for a while and after reading the second article this is what I've come up with.
I've backed up and changed my /etc/init.d/lirc to look like this Code: #! /bin/sh
#
#
case "$1" in
start)
echo -n "Starting lirc daemon:"
echo -n " lircd"
/usr/sbin/lircd -H dev/input -d /dev/input/event2
< /dev/null
;;
stop)
echo -n "Stopping lirc daemon:"
echo -n " lircd"
pkill lircd
echo "."
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage: /etc/init.d/lircd {start|stop|restart}"
exit 1
esac
exit 0
I Had to remap my buttons with irrecord and the result works with 7 buttons that don't map in the kernel. The lircd.conf file is: Code: begin remote
name hauppauge_pvr
bits 16
eps 30
aeps 100
one 0 0
zero 0 0
pre_data_bits 16
pre_data 0x8001
gap 132980
toggle_bit 0
begin codes
Power 0x00CD
1 0x0002
2 0x0003
3 0x0004
4 0x0005
5 0x0006
6 0x0007
7 0x0008
8 0x0009
9 0x000A
0 0x000B
Go 0x003b
Back/Exit 0x001f
Menu 0x0071
Red 0x016B
Green 0x008B
Yellow 0x0038
Blue 0x0029
Ch+ 0x0192
Ch- 0x0193
Vol- 0x0072
Vol+ 0x0073
Ok 0x0025
Mute 0x0179
Blank 0x0074
Full 0x0184
Rewind 0x00A8
Play 0x00CF
Forward 0x0034
Record 0x00A7
Stop 0x0080
Pause 0x0077
Skip 0x00D9
Replay 0x0024
end codes
end remote The 7 keys that don't map in the kernel and result in the error messages like Code: May 14 19:37:57 Mediabox01 kernel: i2c IR (Hauppauge): unknown key: key=0x25 raw=0x17e5 down=0 in /var/log/messages are
003b go
001f back/exit
0038 yellow
0029 Blue
0025 OK
0034 Forward
0024 Replay
I've been unable to figure out how to have the kernel recognize these keycodes short of a re-compile. I've tried setkeycodes which doesn't seem to work. Any idea's are welcome. _________________ KnoppMyth Folding@home

Just to throw in my $.02, I am encountering the same issue with the same errors in /var/log/messages. However, my remote is working, albeit at reduced capability. In other words, sometime I have to hit the button 10 times to get the screen to react, and other times it is very responsive.

I had the same problem in R5E50 and early in the post R5E50 test builds. I'm not sure what cleared it up, but let me recommend a cold power off for 4-5 minutes to force the firmware to be reloaded... I can also post my lirc config files if you're interested. At the time it struck me that something else was running at an elevated priority and either stealing too much CPU time or increasing the latency which caused lirc to miss bits.

That seems to have worked for me too... and all this time I've been doing it the haaaard way.  _________________ KnoppMyth Folding@home

I just tried a cold boot with the power suppy turned off for 10 minutes, but I am still getting the errors in /var/log/messages. I will keep investigating...

Left the machine off for 15 minutes. Hauppauge remote still doesn't work, and now my backend either isn't running or isn't being recognized. Whee.
EDIT: after about 4 reboots, mythbackend started working again. Man am I going to hear about missing the first 20 minutes of Oprah...

I'm interested in this too. I have the grey remote that came with my 250. My remote response is very sluggish most of the time and also have to press a button many times to get it to respond. Sometimes it is quick, but then goes back to being slow/sluggish again. I'm willing to help and test if anyone has any ideas. I really dont know where to start. Control with the k/b is always fast and responsive.

I tried the power off fix as well. No dice.
I was also looking at the /etc/init.d/lirc file. It is more complicated than I can comprehend, but I was wondering about the line that referred to /dev/lirc/0, but that is probably nothing because the file does work for some of you.
When I get some time, I may try Gnarl's solution. However, I'd rather try a full solution rather than partial.

The more I search, the more I find statements like this:
http://wiki.nerdylorrin.net/wiki/Wiki.jsp?page=LIRC: "Errors such as i2c IR (Hauppauge): unknown key: key=0x25 raw=0x37a5 down=0 in /var/log/syslog and intermittenet responsiveness to the remote control in irw can be caused by having both ir_kdb_i2c and lirc_i2c loaded at the same time. Try modprobe -r ir_kdb_i2c."
To reiterate tkoster, maybe all we need to do is remove ir_kbd_i2c. Is this even possible? A simple modprobe -r returns an error because the module is in use. It looks like saa7134 depends on it and saa7134_dvb depends on that. Does it have to be this way, or can saa7134 use lirc_i2c instead?

You could always rename the ir_kbd_i2c module and reboot... The file looks like it's: /lib/modules/2.6.18-chw-13/kernel/drivers/media/video/ir-kbd-i2c.ko
BTW - It look slike an afwul lot of modules are being loaded for no good reason, I've got a pile of useless dvb and saa7134 stuff loaded when all the box has in it at the moment is a couple Hauppauge PVR cards...
The following command will produce a sorted list of unused modules.
Code: lsmod | awk '$3 == 0 { print $1 }' | sort

Good catch. I looked for it once before, but missed it and therefore assumed that Cecil was building it right into the kernel. If the conflict is the source of our problems, removing it should fix things.
As to why all the extra stuff is loaded that we don't need, Cecil tries (and largely succeeds) to make KnoppMyth usable by everyone, with a raft of different cards. The fact that KnoppMyth supports so many is a tribute to our developers. Case in point, saa7134 is used by a boat load of cards. If yours is one, you need it in there if not it is safe to remove it.
I found a list of cards that use it at: http://gentoo-wiki.com/HARDWARE_saa7134
If your card is not on the list, you can try removing it or renaming it to see if your remote starts behaving properly again.

Where is saa7134_dvb even loaded from? I've tried blacklisting it in /etc/modprobe.d/blacklist, but that doesn't seem to work.

Correct me if I'm wrong, but I think the used by column = 0 doesn't necessarily mean it isn't being used, but could be the primary module that was loaded (and loaded the modules it needed) which was not required by other modules _________________ KnoppMyth Folding@home
