This is a loaded machine, and no interrupts are occurring beyond an initial flurry. Before starting up oprofiled I did a pfmdbg --off then --on First, oprofiled.log oprofiled started Wed Oct 15 13:04:12 2003 kernel pointer size: 8 Running perfmon child on CPU0. Waiting on CPU0 Perfmon child up on CPU0 Running perfmon child on CPU1. Waiting on CPU1 Perfmon child up on CPU1 PFM_START on CPU0 PFM_START on CPU1 Shows that both children started up and injected a PFM_START successfully.

Finally, /var/log/messages during this startup period. Note some of it is a bit inter-mixed due to the two children racing to enter stuff in the kernel syslog. This shows that both children have called pfm_start properly etc. Sorry, it's basically impossible to get a debug_ovfl log - even with 20 ints/s (setting CPU_CYCLES:95000000 on my 900 Mhz CPUs), the machine gets so badly flooded it's not possible to get info out of. And I've yet to get overflow info for one of the "some interrupts on a CPU and then nothing" cases. Is there anybody else has actually tried a system-wide session with perfmon on 2.6 across all CPUs ? Is this new territory here ?
