If pmda_linux.so is commented out of /etc/pmcd/pmcd.conf it works.
Tested on Xeon Q9550 and Q5140, fails on both.
Hi Samuel,
This bug has just been fixed upstream. It was reported by someone to the
(upstream) developers directly - google found this bug report as well, so I
just wanted to let you know there's a fix available. pcp-2.9.0 will be released
within the next week, and pushed into Debian unstable shortly thereafter -
that version will be the first release with the fix.
cheers.
