where is my /dev/input/mice on breezy?

[Allison Karlitskaya]

Usually when I start up my computer /dev/input/mice is missing.
Every now and then (about 1 time out of 5) it randomly exists.

/dev/.static/dev/input/mice is still there.

rawr?

[David Pashley (david-davidpashley)]

I've discovered that reloading mousedev works (rmmod mousedev; modprobe
mousedev) and the device is correctly created. I have mousedev in
/etc/modules. It seems that when the module gets loaded during boot udev
fails to notice the device and doesn't create it, but does after the
machine has booted. I don't have anything else that creates a device
node in /etc/modules, so I don't know if it is just mousedev or anything
in /etc/modules.

Hello,

I have the same problem and after booting I restart udev:

/etc/init.d/udev restart

and then I get the missing devices.

Looks like udev is the problem here. Try downgrading udev < 0.060...

I had exactly the same issues, couldn't start X no mice, couldn't load ALSA
hardware...

I downgraded to udev/testing (0.056-3) and everything is working again.

Have a look at http://bugs.debian.org/317626, http://bugs.debian.org/317332
and http://bugs.debian.org/317333. Perhaps these three could be merged.

I just updated to 0.062-1, and now it's not just /dev/input/mice
anymore, but my alsa devices, input devices, nvidia, etc that just isn't
there on boot.

As Noèl mentions, doing /etc/init.d/udev restart after boot fixes it.

Hi,

As asked by udev 0.062 (0.062-4 here), i've installed a custom 2.6.12
kernel on my Sid.

My mouse and alsa driver aren't created anymore and it seems a lot of
devices not needed a created also (ex: tty[a-z]7, ..)

This definitely needs to be investigated. Please report the content of
/etc/udev/ and /etc/udev/rules.d/
Also, are you sure that the relevant drivers have been loaded?

Sure, lsmod after boot has all the modules loaded (snd_intel8x0, psmouse
and mousedev are loaded).

I've also tried to purge udev installation and reinstall it after
without success.

A /etc/init.d/udev restart always fix the problem after the boot.

Here are the content of /etc/udev and /etc/udev/rules.d :

This is interesting, because nothing in udev itself was changed.
(IOW, this bug is even more subtle...)

Are you sure udev is not just deactivated? I think Marco set it up so
that udev detects whether or not 2.6.12 is running, and if it's not
(like in your case 2.6.11) it just stops. Well, that's how I understood
it at least.

Personally I had to temporarily downgrade to sarge's udev, seeing as I
was getting more problems (sbp2 problems) - at least until 2.6.12 enters
debian.

This sucks, I see that you are running 2.6.13rc...

Please reboot with this installed as

Hi,

I set the logging from "err" to "info" in /etc/udev/udev.conf and
I got errors in the syslog like so:
udevinfo[2129]: udev_db.c: unable to read db file '/dev/.udevdb/class@input@mous e0These did not show up with "err" logging. Strange..

Anyway, the problem turned out to be a broken udev_db setting in udev.conf
My udev.conf had it set to "/dev/.udevdb", but because /etc/init.d/udev-mtab
doesn't bind mount that (anymore?), it is not there. After changing it to
"/dev/.static/dev/.udevdb", things were all merry again.

Perhaps this helps?

Cheers,

Joost

No, this is meaningless. /etc/init.d/udev-mtab has nothing to do with
this, the directory is supposed to be created by udevstart and using
/dev/.static/dev/.udevdb is definitely wrong because the file system
will be read only.
Let's try a different approach. What happens if you restore the correct
udev.conf and add "mkdir /dev/.udevdb" to /etc/init.d/udev after the
"warn_if_interactive" line?

You bet it sucks :) I played around a bit and found that it happens
sometimes, sometimes it doesn't. I don't know what it depends on. Even
with the SAME kernel -- sometimes it works, sometimes it doesn't.

I did that. If the device files are not created I get NO logfile. If
the bootup works correctly, I get a log (attached).

This is what other people reported too... It means that for some reason
*no* RUN rule is being honoured, which is even harder to explain.
One of the upstream maintainers suggested to try again with no rules
files (rename /etc/udev/rules.d/).
Myself, I suggest to also try again with "mkdir /dev/.udevdb/" in the
init script after the warn_if_interactive line.

I'm not sure if this is of use to you, considering I'm still using 2.6.11.

But here are the logs generated on boot for udev 0.056-3, 0.060-1, 0.062-1, 0.062-3 and 0.062-4.

These are the symptoms I experience with every udev version.
- 0.056-3: works perfectly
- 0.060-1: a bit of breakage, like /dev/input/mice missing
- 0.062-1: a boatload of breakage, like alsa devices (and lots of others) missing
- 0.062-3 and -4: udev gets disabled on boot, because kernel < 2.6.12, so I guess you can ignore these.

Hi,

First of all, sorry for using telnet as a mail client. Alas, I'm a little
underorganised right now, so this is in ad hoc mode. I'll try to check the
bug log for any replies and necessary further info you might need.

I tried the "mkdir /dev/.udevdb" mod to /etc/init.d/udev and it did not help.
Some other things I tried, broke my system in many funny ways, but still
I could not find the source of the problem. I did find a stray file + dir
/etc/udev/permissions.d/udev.permissions . dpkg knew nothing about it.

Then I purged both udev and hotplug from my system and reinstalled.
This actually broke in the case of udev, report below.

I also tried booting an initrd kernel (2.6.13-rc3) and a straight kernel
(2.6.13-rc3-mm1) and it made no difference wrt the udev problem. It did
bring up another data point, though (fwiw): I changed one hd controller
driver to be modular, which caused a problem in /etc/init.d/checkfs.sh (hde1
device not found). That spawns an early root login, in which I restarted
udev, hoping that it would preempt the alsa/gpm/gdm errors later. Alas, that
does not work either. When later gdm has given up, udev restart still does
make the system completely functional again.

Here's a terminal dump of some of what I did:

thunderbird:/etc/udev# dpkg -S /etc/udev/permissions.d/

Hi,

Here's a quick turnaround. I got udev 0.63 from your website and everything
seems to work fine now. Of course, in the last mail I meant to write "0.63 is
just out", instead of "0.64". Anyway, thanks for the quick response to bugs
and upstream releases.

BTW, during debugging, I noticed that the scripts in the initrd image created
by the mkinitrd package assume devfs support still. Perhaps they need a tune-
up and use udev instead?

Joost

Usually when I start up my computer /dev/input/mice is missing.
Every now and then (about 1 time out of 5) it randomly exists.

/dev/.static/dev/input/mice is still there.

rawr?

[Allison Karlitskaya (desrt)]

Should mention: 'mice' device definitely exists in every other way (ie: opening
the static one works)

also, from dmesg:

Sorry, I'm afraid it's still there. I had installed 0.063-1 a while
back, but only recently installed 2.6.12 (linux-image-2.6.12-1-k7) - as
udev got disabled on boot with 2.6.11, I didn't see the bug of course.

/dev/input/mice is still missing on boot.

Let me know how I can help you chase down this bug.

mousedev is loaded in /etc/modules, just to be sure. Otherwise
everything I can think of (usbhid, bluetooth hidp etc) is all loaded by
hotplug etc.

> Does /sys/class/input/mice/dev exist?

yes.

$ cat /sys/class/input/mice/dev
13:63

> Does running udevstart make the device appear?

yes - doing a find in /dev/ before and after doing udevstart shows it
only affects /dev/input/mice - unlike previous episodes where lots of
other devices (like nvidia) were missing.

Unfortunately, using linux-image-2.6.12-1-k7 2.6.12-2 and udev 0.066-1 I
can still reproduce this bug. After boot certain devices don't show up,
but after running udevstart they seem to be there. Compared to the
previous udev version I checked where only /dev/input/mice was affected,
now my cdrw/dvd devices seem to be affected too:

You will have to try with some extensive debugging then.
Please add to the udev init script commands to mount / (or /var) rw and
start syslogd just before udevstart is called:

mount / -o rw,remount
/etc/init.d/sysklogd start

Set udev_log="debug" in /etc/udev/udev.conf and then reboot with
init=/bin/bash on the kernel command line and manually start udev:

/etc/rcS.d/S02mountvirtfs start
/etc/rcS.d/S04udev start

You should find some useful debugging information in the log.

[joe (joerg-unglaub)]

Where is it thats my question too.

It must be related to kernel 2.6.12. If I boot 2.6.10 the
mice devices work. But under 2.6.12 nope no X.
but my touchpad now works as Synaptics on /dev/psaux.
Next: if the is no /dev/input/mice additionally plugged
externel Mice won't work. :-( you have to configure each one

Subject: Possible fix

Hi,

I set the logging from "err" to "info" in /etc/udev/udev.conf and
I got errors in the syslog like so:
udevinfo[2129]: udev_db.c: unable to read db file '/dev/.udevdb/class@input@mous e0These did not show up with "err" logging. Strange..

Anyway, the problem turned out to be a broken udev_db setting in udev.conf
My udev.conf had it set to "/dev/.udevdb", but because /etc/init.d/udev-mtab
doesn't bind mount that (anymore?), it is not there. After changing it to
"/dev/.static/dev/.udevdb", things were all merry again.

Perhaps this helps?

Cheers,

Joost

No, this is meaningless. /etc/init.d/udev-mtab has nothing to do with
this, the directory is supposed to be created by udevstart and using
/dev/.static/dev/.udevdb is definitely wrong because the file system
will be read only.
Let's try a different approach. What happens if you restore the correct
udev.conf and add "mkdir /dev/.udevdb" to /etc/init.d/udev after the
"warn_if_interactive" line?

You bet it sucks :) I played around a bit and found that it happens
sometimes, sometimes it doesn't. I don't know what it depends on. Even
with the SAME kernel -- sometimes it works, sometimes it doesn't.

I did that. If the device files are not created I get NO logfile. If
the bootup works correctly, I get a log (attached).

This is what other people reported too... It means that for some reason
*no* RUN rule is being honoured, which is even harder to explain.
One of the upstream maintainers suggested to try again with no rules
files (rename /etc/udev/rules.d/).
Myself, I suggest to also try again with "mkdir /dev/.udevdb/" in the
init script after the warn_if_interactive line.

I'm not sure if this is of use to you, considering I'm still using 2.6.11.

But here are the logs generated on boot for udev 0.056-3, 0.060-1, 0.062-1, 0.062-3 and 0.062-4.

These are the symptoms I experience with every udev version.
- 0.056-3: works perfectly
- 0.060-1: a bit of breakage, like /dev/input/mice missing
- 0.062-1: a boatload of breakage, like alsa devices (and lots of others) missing
- 0.062-3 and -4: udev gets disabled on boot, because kernel < 2.6.12, so I guess you can ignore these.

This one works, and correctly works around the bug.
I will upload a fixed package in one or two days.

Subject: more info on udev bug

Hi,

First of all, sorry for using telnet as a mail client. Alas, I'm a little
underorganised right now, so this is in ad hoc mode. I'll try to check the
bug log for any replies and necessary further info you might need.

I tried the "mkdir /dev/.udevdb" mod to /etc/init.d/udev and it did not help.
Some other things I tried, broke my system in many funny ways, but still
I could not find the source of the problem. I did find a stray file + dir
/etc/udev/permissions.d/udev.permissions . dpkg knew nothing about it.

Then I purged both udev and hotplug from my system and reinstalled.
This actually broke in the case of udev, report below.

I also tried booting an initrd kernel (2.6.13-rc3) and a straight kernel
(2.6.13-rc3-mm1) and it made no difference wrt the udev problem. It did
bring up another data point, though (fwiw): I changed one hd controller
driver to be modular, which caused a problem in /etc/init.d/checkfs.sh (hde1
device not found). That spawns an early root login, in which I restarted
udev, hoping that it would preempt the alsa/gpm/gdm errors later. Alas, that
does not work either. When later gdm has given up, udev restart still does
make the system completely functional again.

Here's a terminal dump of some of what I did:

thunderbird:/etc/udev# dpkg -S /etc/udev/permissions.d/
dpkg: /etc/udev/permissions.d/ not found.
thunderbird:/etc/udev# rm -r permissions.d/

Subject: udev 0.63 fixes problem

Hi,

Here's a quick turnaround. I got udev 0.63 from your website and everything
seems to work fine now. Of course, in the last mail I meant to write "0.63 is
just out", instead of "0.64". Anyway, thanks for the quick response to bugs
and upstream releases.

BTW, during debugging, I noticed that the scripts in the initrd image created
by the mkinitrd package assume devfs support still. Perhaps they need a tune-
up and use udev instead?

Cheers,

Joost

Sorry, I'm afraid it's still there. I had installed 0.063-1 a while
back, but only recently installed 2.6.12 (linux-image-2.6.12-1-k7) - as
udev got disabled on boot with 2.6.11, I didn't see the bug of course.

/dev/input/mice is still missing on boot.

Let me know how I can help you chase down this bug.

mousedev is loaded in /etc/modules, just to be sure. Otherwise
everything I can think of (usbhid, bluetooth hidp etc) is all loaded by
hotplug etc.

> Does /sys/class/input/mice/dev exist?

yes.

$ cat /sys/class/input/mice/dev
13:63

> Does running udevstart make the device appear?

yes - doing a find in /dev/ before and after doing udevstart shows it
only affects /dev/input/mice - unlike previous episodes where lots of
other devices (like nvidia) were missing.

Unfortunately, using linux-image-2.6.12-1-k7 2.6.12-2 and udev 0.066-1 I
can still reproduce this bug. After boot certain devices don't show up,
but after running udevstart they seem to be there. Compared to the
previous udev version I checked where only /dev/input/mice was affected,
now my cdrw/dvd devices seem to be affected too:

You will have to try with some extensive debugging then.
Please add to the udev init script commands to mount / (or /var) rw and
start syslogd just before udevstart is called:

mount / -o rw,remount
/etc/init.d/sysklogd start

Set udev_log=3D"debug" in /etc/udev/udev.conf and then reboot with
init=3D/bin/bash on the kernel command line and manually start udev:

/etc/rcS.d/S02mountvirtfs start
/etc/rcS.d/S04udev start

You should find some useful debugging information in the log.

Hi,
I use Version: 0.068-1 and kernel 2.6.12.=20
After booting there is still no /dev/input/mice.
If I restart udev everything works fine.

I just tried debugging:

0. (before rebooting I set udev_log="debug" in /etc/udev/udev.conf)
1. boot Debian linux-image-2.6.12-1-k7 with init=/bin/bash
2. mount / -o rw,remount
3. /etc/rcS.d/S02mountvirtfs start
4. /etc/init.d/sysklogd start
5. modprobe ohci_hcd (hotplug loads the other necessary modules, like
usbhid, and mousedev - doublechecked they are loaded in dmesg/lsmod)
6. /etc/rcS.d/S04udev start

... result: /dev/input/mice _is_ present! (annoying, as it makes it
harder to replicate/simplify the bug)

However I failed to capture any relevant bits of syslog information -
syslog only contains hotplug messages like:
Aug 24 22:32:55 (none) input.agent[1528]: mousedev: loaded
successfully

I guess we're still not closer to figuring out what's going on.

Actually, they are on to something because I had just found out
something significant.

I had 2 things in my /etc/modules:

mousedev
ide-cd

The reason why I added mousedev is that (quite) a while back it wouldn't
get automatically loaded. ide-cd was a debian default if I am not
mistaken.

I commented both out, and on reboot /dev/input/mice was there!

Just to make sure there were no other devices missing, I started
udevstart again and compared the before and afters:

--- dev_before_udevstart.txt 2005-08-25 16:20:35.000000000 +0200
+++ dev_after_udevstart.txt 2005-08-25 16:20:54.000000000 +0200
@@ -1,2 +1,5 @@
 /dev/
+/dev/dvd1
+/dev/cdrw1
+/dev/cdrom1
 /dev/vcsa1

Now this is weird (and new) - there's no clear reason why extra
(unecessary) dev nodes are made afterwards, and why he didn't make them
in the first place (on boot). The nodes point to the same thing:

lrwxrwxrwx 1 root root 3 Aug 25 16:19 /dev/dvd -> hdc
lrwxrwxrwx 1 root root 3 Aug 25 16:20 /dev/dvd1 -> hdc

(similarly for cdrw/cdrw1, and cdrom/cdrom1 - there's no dvd0)

I guess it's because I commented out ide-cd too ...?

It's still very weird that modules listed in /etc/modules have this
effect on udev. In the end the same modules are loaded, just at
different times (and maybe twice?).

Strange, the event seems to get lost. If you restore the
failing setup and add a "sleep 1" before udevstart, does it work then?

No, this is ok. %e is used, i think. That %e is not very smart and just
increases the number if the udevdb is not cleared before the run of
udevstart.

Looks like the Ubuntu people have found a workaround, but I do not know
why unix.ko is not always being correctly autoloaded.

(Anyway, a generic kernel with modular AF_UNIX is stupidly broken.)

We traced the race condition here, FYI: It seems that the 'unix' kernel
module isn't always loaded, so udevsend can't talk to udevd. In our
testcases, it looks like forcing it to be loaded in advance does the
trick.

I would like the users experiencing this bug to confirm that AF_UNIX is
modular on their system and then boot with init=3D/bin/bash, check that
the module is not loaded and check if it is after sending an event
this way:

ACTION=3Dadd DEVPATH=3D/devices/system/cpu/cpu0 SUBSYSTEM=3Dcpu /sbin/udevs=
end

udevd should be started too. If this is not happening, then we have
a problem.
