Just a me too on this one. I ran into this on a 10.04.3 system with some Matlab jobs that have been running for a couple of weeks.

For what it's worth, htop seems to work properly and show the CPU usage of these processes.
Here's some system info:
# uname -a Linux myhost 2.6.32-37-generic #81-Ubuntu SMP Fri Dec 2 20:32:42 UTC 2011 x86_64 GNU/Linux
# cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04.3 LTS"
Let me know if any other info would be helpful while these jobs are still running. :-)
