I have a Dell Poweredge 400SC, with a Hyper threaded P4/1GB of ram, ATI Radeon 9600 based video. Load average jumps to the 4's, and stays there - while each cpu in the hyper thread shows about 50% idle time.

The other thing is I may have botched moving my scheduler on top of smtnice. I hadn't tested that too well (I have an HT system, but it doesn't run X). If you get time, could you try turning off CONFIG_SCHED_SMT - if that still doesn't help, try turning off hyperthreading completely. Thanks.
