Comment 9 for bug 115616

Just upgrading to gutsy and have the same issue. Kernel log is full of messages:

[ 2860.300000] device-mapper: ioctl: error adding target to table
[ 2860.300000] device-mapper: table: 254:0: linear: dm-linear: Device lookup failed

root@orion:~# ps aux | grep udev
root 2669 56.8 6.7 27476 25852 ? S<s 19:15 31:23 /sbin/udevd --daemon
root 21697 0.0 6.7 27608 25944 ? S< 20:10 0:00 /sbin/udevd --daemon
root 21699 0.0 0.1 2020 588 ? S< 20:10 0:00 /lib/udev/watershed /sbin/evms_activate

Please note, that the /sbin/evms_activate process and one udevd show up then hide again and again (with different pid). udevd process with pid 2669 eats all idle CPU according to top.

I have removed evms (and then reboot) to 'fix' this issue since I don't need evms.
