My customer is having an issue with the '-a' command in AMDuProfPcm. The command fails with it included:

$ /opt/AMDuProf_5.0-1479/bin/AMDuProfPcm -a -O /tmp

configureDfPmcEvent failed...

: Invalid argument

Whereas the same command without the '-a' allows a run to begin and collection starts.

Can anyone offer any advice to get the '-a' parameter working?
