Hi, I hope you could understand my poor english. I'm running a Kubuntu hardy with this huge problem: input peripherals are randomly associated with the devices in /proc/bus/input/devices, but they work only if associated with one of them. Here the example, this is a good one:

Everything works: I can use my remote for the tvcard, the mouse works and the pc speaker do. Sometimes the remote is in "...event6" and "...input6", the mouse in "....input5" and "...event5" and when it happens they don't work. Sometimes the pc speaker steal the place of the remote or the mouse, so I have wesnoth without sound and the mouse or the remote broken.
Is there something I can do to stop this?

Has this happened with other distrubutions that you have tried?....if so....I suspect you have the wrong bios options

2) have you got your motherboard manual or can you download it....so you can see the various options in your bios

3) what is the name of the bios supplier? award or phoenix etc

4) what is the name of your bootloader? is it lilo or grub or what?

5) assuming its grub you add (with root powers so save works).to your /boot/grub/menu.lst kernel line at end..........pci=routeirq

but please be aware that we can only make one change at a time.

6) also you may have a interrupt conflict.....a conflict is more serious than a interrupt that is shared.

conflicts normally occur if your bios is set to pic and not apic

open a shell and run commands
if you see 2 or more devices on the same line you either have a share or conflict but the lines at the bottom of the command as above will tell us so post the output please

oops you do not need root powers to run cat command and here is my output
cat /proc/interrupts

notice the APIC shows up and a number of devices SHARE the same interrupt but ERR is zero so there are no errors

The output of "cat /proc/interrupts" is:

Do you see something wrong? It's the first time it happens, I have used for a long time suse (9.1,9.2,9.3) , kanotix and pclinuxos (0.92,0.93,2007,2008). My bios is made by phoenix.
I have grub, but I don't understand this:

What does it mean? I have to change only one kernel line at a time?

interrupts looks fine....now try the grub boot parameter please

First of all, here it is my menu.lst:

Do I write it right?
By the way, I have booted 2 times the generic kernel and 2 times the rt kernel: the generic one seems to work now, the rt doesn't: maybe this option is not supported by that kernel?

Unfortunately on the third boot pcspeaker took the mouse's place even with the generic kernel.

did you write it correctly....yes....your observations are good as well...I do not use ubuntu but I have requests for you.

1) from now on ignore the recovery kernels pls
2) try only the generic and whatever the rt is....btw in your package manager there should be a description of rt...if you find it let me know pls....it may help others as well

now for both...kernels...upload your /var/log/syslog to a online site that you can link to....if you do not have one...use www.ripway.com and its free.

this is more work for you...and for others to read....but these logs tend to be large and may turn off others reading it so the link posted here is easier on the eye if you agree?

3) for each kernel I would like a link for the output of your cat /proc/interrupts AND I would like a link for each for the output of lsmod command....this lsmod command may not be useful...but we won't know until we read it eh?

4) can I suggest you name each file something like
gen-syslog and rt-syslog
gen-irq (for interrupts) and rt-irq
gen-lsmod and rt-lsmod

5) Please remove that grub parameter from your (recovery mode) kernel kernel lines

Now the other questions you ask and my reasons are:

to troubleshoot...you only want to make change at a time...so you know what u did and so know what has changed the effects.

2) did you have the same issue with the other distros?......what was wrong with them if it did not? as if I or others can not help....it may not be you....I suspect it never was...but your choice of distro....leaping ahead pclinuxos is based on mandriva....heh heh

3) knowing it is phoenix allows us to think about whether we should flash it...and where to get the flash files.....but altho I am experienced at it....it is the last resort and not recommended in case we can solve it for software issues.

again...if your other distros did not have the problem....it is not your bios...but until you answer I am not sure ok?

First of all, thanks a lot for you help, really. Then, here is the description of the rt-kernel:

I can't install more distros because my burner is broken, but the ones I used in the past worked well.

bad luck on burner....and at least we know this is a distro specific issue and you previously had working hw with other distros you tried.

$50 burner is looking good

2) easy stuff first....
http://h1.ripway.com/aus9/sloteel/irq-diff.png

see the main diff is irq 21 for flgx which is for graphics...I used to think that it was ati but then I spotted in your lsmod.... nvidia graphics.

3) I propose the following suggestions

assume from now on....boot only the generic pls

a) if you do not need pcspeaker, you can get rid of it completely

ubuntu should have a folder in /etc/ called module or modules whatever....you will find files called blacklist

just add a new line to one with the new line

pcspkr

b) if you do need it.....run a command with root powers after you have booted

....check your input devices first

modprobe pcskr

if there are no conflicts now add it to /etc/rc.local with root powers and see if on reboot your input devices is still good.

pls report if any success....but do a few reboots so we have more confidence it is the pcskr.

No, it still doesn't work, but maybe I forgot something important:
To make the ircommand work I put in rc.local this line:

/usr/sbin/lircd -H dev/input -d /dev/input/event5

I tried to erase "-d /dev/input/event5" and reboot: even with the mouse in "...input5" (the place that the remote should have) the mouse itself works.... but the ircommand doesn't.
Following the guide I use to configure the tvcard to indicate the device is a condition not escapable. Maybe this is the root of the problem? I have used this trick in every distro I got.

not that I have infrared remote but you can see your device in here and can you name pls
http://lirc.sourceforge.net/remotes/


EDIT

remove all work you did on attempt for pcskr since it failed.

2) you won't like it but please try this

remove that rc.local line that fixes ir device to event5
reboot
run your cat /proc/bus/input/devices command to see what events are free
run manually /usr/sbin/lircd -H dev/input -d /dev/input/eventN where N is a free number

My remote isn't there: I have one bundled with the tv card, a lifeview flyvideo 2000.
After a reboot as in 2) I got this:

And irKick said that there weren't any remotes available. So I lunched "sudo /usr/sbin/lircd -H dev/input -d /dev/input/event5" and it stars to work.
I know that /dev/input/event5 is the place where it always worked but after 10 boots I couldn't have it in another place! But I think that this is the problem. Maybe I should write a script that read the content of /proc/bus/input/devices and sets the line I use to start lircd...

I hopefully solved the problem with a very rough solution. First, I blacklisted pcspkr: I don't really need it, and its presence is going to complicate the situation. Then, I made this script:
This script start lircd with "-d /dev/input/event4" if the remote is in event4, "-d /dev/input/event5" if it is elsewhere, but without the pc speaker I'm confident that the remote will be only in input4 or input5. So I copied this in /usr/bin and I wrote /usr/bin/remotestart (the name of the script) in rc.local. Now I'm studying bash programming to upgrade the script and make it handle more situations.

Aus9, thanks a lot for your time, your help and your learnings.
