There is a backport of the CFS scheduler to 2.6.21, see

Hi, Simon:

I will try that after the thanksgiving holiday to find out whether the odd behavior will show up using 2.6.21 with back ported CFS.

would be also nice to test this with 2.6.24-rc4.

Hi, Ingo:

I just ran the same test on two 2.6.24-rc4 kernels: one with CONFIG_FAIR_GROUP_SCHED on and the other with CONFIG_FAIR_GROUP_SCHED off. The odd behavior I described in my previous e-mails were still there for both kernels. Let me know If I can be any more help. Thank you.
