Hello all,

I just upgraded to udev-210, and followed the instructions for restarting it:

Code:

/etc/init.d/udev --nodeps restart


but now I show that it has crashed:

Code:

udev # /etc/init.d/udev status
 * status: crashed


and dmesg isn't providing a lot of information:

Code:

[8046922.782935] systemd-udevd[8211]: worker [8260] exit
[8046922.782938] systemd-udevd[8211]: worker [8260] cleaned up
[8046954.273454] systemd-udevd[8211]: validate module index
[8046954.273475] systemd-udevd[8211]: Check if link configuration needs reloading
[8046954.273510] systemd-udevd[8211]: udevd message (EXIT) received
[8046954.385448] systemd-udevd[8211]: unload module index
[8046954.385481] systemd-udevd[8211]: Unloaded link configuration context
[8046954.400524] systemd-udevd[8340]: starting version 210


Any suggestions on where to look next?

Thank you preemptively.

Cheers,
Nathan Zachary

I would go with --debug --restart to see if it help get what's going on.

I've sometimes had messages about crashing show up in /var/log/messages.

Note: if you are using systemd, then you would need to look at it's logging output (I don't use it so I don't have any further advice on this point)

Anon : of course i suck at systemd too :)
But to me, i was thinking systemd provide udev service, so one with udev presence imply systemd absence.

I wasn't sure what "systemd-udevd" implied since I use an old version of udev and on my system is shows as just "udevd".

For starters, enable debugging in /etc/conf.d/udev, like:

Code:

udev_monitor="YES"
udev_debug="YES"


And in /etc/udev/udev.conf, like:

Code:

udev_log="info"


Other possible values are "err" and "debug". Honestly, I'm not sure which would be best in your case, I've managed with "info"
They are listed in bottom of `man systemd-udevd`

You should get various different type of logs in /var/log/messages, /run/udevmonitor.log, /run/udevdebug.log

You might also be hitting a race, on a running system, when you do `/etc/init.d/udev --nodeps restart`, it might be better to take the dive and reboot

Good luck getting more debug information!

@krinn personellement et très amicalement : Tu veux être sûr que tout le monde comprend que tu ne cherches qu'à faire rire.
Donc... tu sais très bien que tout le monde ne comprendra pas...
alors... à quoi bon ?
Et puis... à mon opinion... et bien... se citer soi-même... ça fait un peu... heu... enfin... tu vois ce que je veux dire... :roll: disgracieux!

Finalement, je crois que je préfère quand tu dis des bêtises sur l'optimisation de gcc... :wink: and :P
