linux-image-2.6.22 causes udevd to eat-up CPU

[Enver ALTIN]

Binary package hint: linux-image-2.6.22-6-generic

On my system, that is a Compaq nx7010 laptop, after upgrading from 2.6.20-15 to any 2.6.22 version udevd eats up more than 70% CPU power and adds loops of these to kern.log:

Jun 11 22:21:33 localhost kernel: [ 560.416000] device-mapper: table: 254:0: linear: dm-linear: Device lookup failed

Jun 11 22:21:33 localhost kernel: [ 560.540000] device-mapper: ioctl: error adding target to table

I've read over the Changelog to see if I can find something useful to find the root of the problem, nothing yet. I'm not sure if this is a udev bug, so I'll file this against the linux-image-2.6.22-generic package.

Thanks,

Can confirm.
I have this same on a SMP 2xAthlon machine. It was so bad that I gave up on booting and booted back into 2.6.20 series.
I have a LVM partition on a disk, nothing fancy, single partition there.
This is feisty fully dist-upgraded to current gutsy.

I confirm this bug on iMac G5 rev C. ubuntu installed since dapper and dist-upgraded for each development version (now gutsy).

This is 'Needs Info' now, what further information is needed?

On my case upgrading to 2.6.22 failed completely, for two reasons:

1. vesafb is not provided on 2.6.22-6 (different issue, and I will open a bug on it);
2. my system *never* ends booting: it loops for ever and ever (measured by a standard clock as being 30 minutes in duration) putting out messages similar to the shown in the bug description, followed by an error trying to identify DM-7 (whatever it would be), and back to the messages above.

Unfortunately I do not have a digital camera, so I cannot capture the messages.

Pasi's question above is correct: what info is needed?

I have the same problem,
gutsy on a fujitsu siemens amilo pro v2030 laptop, celeron m processor, mostly via insides.

mine boots slowly, but udevd will keep eating up 30-100% of my processor until i sudo killall udevd && sudo udevd - at which point the problem ceases, and udevd runs apparently normally.

[Expired for linux-source-2.6.22 (Ubuntu) because there has been no activity for 60 days.]

This was fixed for me with 2.6.22-11.

I just ran into this bug on 2.6.22-12 after completing my upgrade to Gutsy Beta on my
Gateway 7330 laptop. Udevd had the CD/DVD-RW going crazy too. Had to leave it open
until I could killall udevd and restart it.
