Could you give more details as to what you were trying to measure on which
program, what are the console messages. You can turn on perfmon kernel
debugging messages by using pfdbg --on. This program is part of the pfmon
package. I can't say if 2.4.10 would buy you anything until I get more infos
on your problem.
