Kernel was sucessfully rebooted; /dev/profile device was created as major 192, minor 0. When I run kernprof command it complained " /dev/profile: No such device". I followed the instruction posted on web. 2) If I run the most recent v2.4.0 kernel, do I need to download the corresponing patch, or it's OK to use any patch for v2.4.0-testxx?

Yes. Or more accurately, "maybe". I've tried to move the patch forward to various 2.4.0-* releases, but I haven't tested (and in some cases haven't compiled) the profiling patch against ia64. It's near the top of my to-do list. Available patches: -test7, -test8, -test10, -test11, and the final 2.4.0. John Hawkes hawkes@engr.sgi.com
