Gutsy and 100% CPU usage... udevd going nuts.

This article seems to have the fix:
Upgrade to Ubuntu Gutsy - emvs and udevd 100% cpu usage - aka udevd going nuts

One typo I noticed: He refers to /etc/init.d/udevd instead of /etc/init.d/udev.

The corrected steps:
# apt-get remove evms
# /etc/init.d/udev stop
# /etc/init.d/udev start
