Re: [perfmon2] pfmon error on Montecito processor
Hi,
you're hitting the same errata handling code.
The kernel thinks you still have threads on or that they can
be enabled at runtime.
To actually disable threads, and if I recall correctly, you must use
cpuconfig at th
s on, I have 16 of them.

please find the log in attachment.
Yes, now I have 8 processors through my 4 Montecito CPU. When hyper-threading
is on, I have 16 of them.

Yes, that's normal, it just enabled kernel level debugging output.
grab what you have about perfmon in /var/log/syslog.

Hi all:
Now I'm using a dual-core Itanium2 processor with perfmon kernel 2.81,
pfmlib and pfmon V3.7.
I have used pfmon3.2 with kernel 2.0 for long time. I updated the perfmon
kernel to 2.81 recently and now I get problems. When I count for more than
6 events with pfmon, I get the error message "c
